A class of zeta functions that extends the class of Epstein's was
recently brought to my attention by
Prof. E. Elizalde of M.I.T. They
are spectral zeta functions associated with a quadratic + linear + constant
form in any number of dimensions. Elizalde has developed formulas
for them which extend the famous ChowlaSelberg formula.

[abstract:] "We establish rigorously the regularization of the $p$adic open string amplitudes, with Chan–Paton rules and a constant Bfield, introduced by Goshal and Kawano. In this study we use techniques of multivariate local zeta functions depending on multiplicative characters and a phase factor which involves an antisymmetric bilinear form. These local zeta functions are new mathematical objects. We attach to each amplitude a multivariate local zeta function depending on the kinematics parameters, the Bfield and the Chan–Paton factors. We show that these integrals admit meromorphic continuations in the kinematic parameters, this result allows us to regularize the Goshal–Kawano amplitudes, the regularized amplitudes do not have ultraviolet divergences. Due to the need of a certain symmetry, the theory works only for prime numbers which are congruent to $3$ modulo $4$. We also discuss the limit $p$ tends to $1$ in the noncommutative effective field theory and in the Ghoshal–Kawano amplitudes. We show that in the case of four points, the limit $p$ tends to $1$ of the regularized Ghoshal–Kawano amplitudes coincides with the Feynman amplitudes attached to the limit $p$ tends to $1$ of the noncommutative Gerasimov –Shatashvili Lagrangian."

Such Lagrangians have their origin in Lagrangian for a single padic string and contain the Riemann zeta function with the 'Alembertian in its argument. In particular, we present a new Lagrangian obtained by an additive approach which takes into account all padic Lagrangians. The very attractive feature of this new Lagrangian is that it is an analytic function of the d'Alembertian. Investigation of the field theory with Riemann zeta function is interesting in itself as

[abstract:] "pAdic strings are important objects of string theory, as well as of padic mathematical physics and nonlocal cosmology. By a
concept of adelic string one can unify and simultaneously study various aspects of ordinary and padic strings. By this way, one can consider
adelic strings as a very useful instrument in the further investigation of modern string theory. It is remarkable that for some scalar padic strings
exist effective Lagrangians, which are based on real instead of padic numbers and describe not only fourpoint scattering amplitudes but also
all higher ones at the tree level. In this work, starting from padic Lagrangians, we consider some approaches to construction of effective field
Lagrangians for padic sector of adelic strings. It yields Lagrangians for nonlinear and nonlocal scalar field theory, where spacetime nonlocality
is determined by an infinite number of derivatives contained in the operatorvalued Riemann zeta function. Owing to the Riemann zeta function
in the dynamics of these scalar field theories, obtained Lagrangians are also interesting in themselves."

[abstract:] "We consider theories with timedependent Hamiltonians which alternate between being bounded and unbounded from below. For appropriate frequencies dynamical stabilization can occur rendering the effective potential of the system stable. We first study a free field theory on a torus with a timedependent mass term, finding that the stability regions are described in terms of the phase diagram of the Mathieu equation. Using number theory we have found a compactification scheme such as to avoid resonances for all momentum modes in the theory. We further consider the gravity dual of a conformal field theory on a sphere in three spacetime dimensions, deformed by a doubletrace operator. The gravity dual of the theory with a constant unbounded potential develops big crunch singularities; we study when such singularities can be cured by dynamical stabilization. We numerically solve the Einsteinscalar equations of motion in the case of a timedependent doubletrace deformation and find that for sufficiently high frequencies the theory is dynamically stabilized and big crunches get screened by black hole horizons."

[abstract:] "We study the distribution of graded degrees of freedom in classically stable oriented closed string vacua and use the RankinSelberg transform to link it to the finite oneloop vacuum energy. In particular, we find that the spectrum of physical excitations not only must enjoy asymptotic supersymmetry but actually, at very large mass, bosonic and fermionic states must follow a universal oscillating pattern, whose frequencies are related to the zeros of the Riemann zetafunction. Moreover, the convergence rate of the overall number of the graded degrees of freedom to the value of the vacuum energy is determined by the Riemann hypothesis. We discuss also attempts to obtain constraints in the case of tachyonfree openstring theories."

[abstract:] "We study asymptotics and error estimates of long horocycle averages of automorphic functions with notsomild growing conditions at the cusp. For modular functions of rapid decay, it is a classical result that a certain value of the power in the error estimate is equivalent to the Riemann hypothesis. For modular functions of polynomial growth, we study how asymptotics are modified, by devising and unfolding trick with a twodimensional lattice theta series. For modular functions of exponential growth, we gain insights on the horocycle average asymptotic, by translating this quantity into a states counting function in heterotic string theory. Consistency conditions for the heterotic string physical spectrum, lead to a special bound on the modular function exponential growth. String theory suggests that automorphic functions in the growing class below that bound should have convergent horocycle average."

Hypothesis and short distance fermionic Green's functions" (preprint 04/05)

modified dispersion relation and short distance parameter a is given by the Lerch
zeta function. The Green's function is defined on a cylinder of radius R and we show
that the condition R = a yields the Riemann zeta function as a quantum
transition amplitude for the fermion. We formulate the Riemann hypothesis physically as a
nonzero condition on the transition amplitude between two special states associated with
the point of origin and a point half way around the cylinder each of which are fixed points
of a $Z_2$ transformation. By studying partial sums we show that that the transition
amplitude formulation is analogous to neutrino mixing in a low dimensional context. We also
derive the thermal partition function of the fermionic theory and the thermal divergence at
temperature 1/a. In an alternative harmonic oscillator formalism we discuss the
relation to the fermionic description of two dimensional string theory and matrix models.
Finally we derive various representations of the Green's function using energy momentum

[abstract:] "We investigate the physical interpretation of the Riemann zeta function as a FZZT brane partition function associated with a matrix/gravity correspondence. The HilbertPolya
operator in this interpretation is the master matrix of the large N matrix model. Using a related function $\Xi(z)$ we develop an analogy between this function and the Airy function Ai(z) of the
Gaussian matrix model. The analogy gives an intuitive physical reason why the zeros lie on a critical line. Using a Fourier transform of the $\Xi(z)$ function we identify a Kontsevich integrand.
Generalizing this integrand to $n \times n$ matrices we develop a Kontsevich matrix model which describes n FZZT branes. The Kontsevich model associated with the $\Xi(z)$ function is given by
a superposition of Liouville type matrix models that have been used to describe matrix model instantons."

understand why the zeros of the FZZT partition function, which is the Airy function, lie on the real axis. We also
introduce an iterative procedure that can describe the Riemann $\Xi$ function as a deformed minimal model whose
deformation parameters are related to a Konsevich integrand. Finally we discuss the relation of our work to other
approaches to the Riemann $\Xi$ function including expansion in terms of MeixnerPollaczek polynomials and

We show that the nearhorizon dynamics of a massive scalar field in the Schwarzschild black hole spacetime, under a reasonable boundary condition, gives rise to energy eigenvalues that coincide with the Riemann zeros. In achieving this result, we exploit the Bekenstein conjecture of black hole area quantization, and argue that it is responsible for the breaking of the continuous scale symmetry of the near horizon dynamics into a discrete one."

[abstract:] "Quantum gravity is expected to gauge all global symmetries of effective theories, in the ultraviolet. Inspired by this expectation, we explore the consequences of gauging CPT as a quantum boundary condition in phase space. We find that it provides for a natural semiclassical regularisation and discretisation of the continuous spectrum of a quantum Hamiltonian related to the Dilation operator. We observe that the said spectrum is in correspondence with the zeros of the Riemann zeta and Dirichlet beta functions. Following ideas of Berry and Keating, this may help the pursuit of the Riemann hypothesis. It strengthens the proposal that this quantum Hamiltonian captures the dynamics of the scattering matrix on a Schwarzschild black hole background, given the rich chaotic spectrum upon discretisation. It also explains why the spectrum appears to be erratic despite the unitarity of the scattering matrix."

[abstract:] "The microscopic spectrum of halfBPS excitations in toroidally compactified heterotic string theory has been computed exactly through the use of results from analytic number theory. Recently, similar quantities have been understood macroscopically by evaluating the gravitational path integral on the Mtheory lift of the AdS2 nearhorizon geometry of the corresponding black hole. In this paper, we generalize these results to a subset of the CHL models, which include the standard compactification of IIA on $K3 \times T2$ as a special case. We begin by developing a Rademacherlike expansion for the Fourier coefficients of the partition functions for these theories, which are modular forms for congruence subgroups. We then interpret these results in a macroscopic setting by evaluating the path integral for the reducedrank $N=4$ supergravities described by these CFTs."

[abstract:] "In this article we present the postNewtonian (pN) coefficients of the energy flux (and angular momentum flux) at infinity and event horizon for a particle in circular, equatorial orbits about a Kerr black hole (of mass $M$ and spinparameter $a$) up to 20pN order. When a pN term is not a polynomial in $a/M$ and includes irrational functions (like polygamma functions), it is written as a power series of $a/M$. This is achieved by calculating the fluxes numerically with an accuracy greater than 1 part in 10600. Such high accuracy allows us to extract analytical values of pN coefficients that are linear combinations of transcendentals like the Euler constant, logarithms of prime numbers and powers of $\pi$. We also present the 20pN expansion (spinindependent pN expansion) of the ingoing energy flux at the event horizon for a particle in circular orbit about a Schwarzschild black hole.
E. Belbruno, "On the regularizability of the Big Bang singularity" (preprint 05/2012)
[abstract:] "The singularity for the big bang state can be represented using the generalized anisotropic Friedmann equation, resulting in a system of differential equations in a central force field. We study the regularizability of this singularity as a function of a parameter, the state variable, $w$. We prove that for $w >1$ it is regularizable only for $w$ satisfying relative prime number conditions, and for $w \leq 1$ it can always be regularized. This is done by using a McGehee transformation, usually applied in the three and fourbody problems. This transformation blows up the singularity into an invariant manifold. This has implications on the idea that our universe could have resulted from a big crunch of a previous universe, assuming a Friedmann modeling."

We show how these sums can be obtained naturally from the functional integral of supergravity in asymptotically AdS_2 space for a class of black holes. They are essentially topological in origin and correspond to chargedependent phases arising from the various gauge and gravitational Chern–Simons terms and boundary Wilson lines evaluated on Dehnfilled solid 2torus. These corrections are essential to obtain an integer from supergravity in agreement with the quantum degeneracies, and reveal an intriguing connection between topology, number theory, and quantum gravity. We give an assessment of the current understanding of quantum entropy of black holes."

A. Sugamoto, "Factorization of number into prime numbers viewed as
decay of particle into elementary particles conserving energy" (preprint 10/2009)
[abstract:] "Number theory is considered, by proposing quantum mechanical models and stringlike models at zero and finite
temperatures, where the factorization of number into prime numbers is viewed as the decay of particle into elementary particles
conserving energy. In these models, energy of a particle labeled by an integer $n$ is assumed or derived to being proportional
to $\ln n$. The oneloop vacuum amplitudes, the free energies and the partition functions at finite temperature of the stringlike
models are estimated and compared with the zeta functions. The $SL(2, {\bf Z})$ modular symmetry, being manifest in the free
energies is broken down to the additive symmetry of integers, ${\bf Z}_{+}$, after interactions are turned on. In the dynamical
model existing behind the zeta function, prepared are the fields labeled by prime numbers. On the other hand the fields in our
models are labeled, not by prime numbers but by integers. Nevertheless, we can understand whether a number is prime or not prime
by the decay rate, namely by the corresponding particle can decay or can not decay through interactions conserving energy. Among
the models proposed, the supersymmetric stringlike model has the merit of that the zero point energies are cancelled and the
energy levels may be stable against radiative corrections."
M. Cvetič, I. GarcíaEtxebarria, J. Halverson, "On the computation of nonperturbative effective potentials in the string theory landscape  IIB/Ftheory perspective" (preprint 09/2010)
[abstract:] "We discuss a number of issues arising when computing nonperturbative effects systematically across the string theory landscape. In particular, we cast the study of fairly generic physical properties into the language of computability/number theory and show that this amounts to solving systems of diophantine equations. In analogy to the negative solution to Hilbert's 10th problem, we argue that in such systematic studies there may be no algorithm by which one can determine all physical effects. We take large volume type IIB compactifications as an example, with the physical property of interest being the lowenergy nonperturbative Fterms of a generic compactification. A similar analysis is expected to hold for other kinds of string vacua, and we discuss in particular the extension of our ideas to Ftheory. While these results imply that it may not be possible to answer systematically certain physical questions about generic type IIB compactifications, we identify particular CalabiYau manifolds in which the diophantine equations become linear, and thus can be systematically solved. As part of the study of the required systematics of Fterms, we develop technology for computing Z_2 equivariant line bundle cohomology on toric varieties, which determines the presence of particular instanton zero modes via the Koszul complex. This is of general interest for realistic IIB model building on complete intersections in toric ambient spaces."

Riemann surfaces and the perfect numbers" (preprint 12/1998)
"The equality between the number of odd spin structures on a Riemann surface of genus $g$, with $2^g  1$ being
a Mersenne prime, and the even perfect numbers, is an indication that the action of the modular group on the set
of spin structures has special properties related to the sequence of perfect numbers. A method for determining
whether Mersenne numbers are primes is developed by using a geometrical representation of these numbers. The
connection between the nonexistence of finite odd perfect numbers and the irrationality of the square root of
twice the product of a sequence of repunits is investigated, and it is demonstrated, for an arbitrary number of
prime factors, that the products of the corresponding repunits will not equal twice the square of a rational
number."

constants of the fundamental interactions (including the cosmological constant) are determined via certain
topological invariants of manifolds forming finite ensembles of 3D Seifert fibrations. The characteristic values
of the coupling constants are explicitly calculated as the set of rational numbers (up to the factor
2) on the basis of a hypothesis that these values are proportional to the mean
relative fluctuations of discrete volumes of manifolds in these ensembles. The discrete volumes are calculated
using the standard Alexandroff procedure of constructing T_{0}discrete spaces realized
as nerves corresponding to characteristic canonical triangulations which are compatible with the Milnor
representation of Seifert fibered homology spheres being the building material of all used 3D manifolds.
Moreover, the determination of all involved homology spheres is based on the first nine prime numbers

"Justification of the zeta function renormalization in rigid string model"
"A consistent procedure for regularization of divergences and for the
subsequent renormalization of the string tension is proposed in the framework
of the oneloop calculation of the interquark potential generated by the
PolyakovKleinert string. In this way, a justification of the formal treatment
of divergences by analytic continuation of the Riemann and EpsteinHurwitz
zeta functions is given. A spectral representation for the renormalized
string energy at zero temperature is derived, which enables one to find
the Casimir energy in this string model at nonzero temperature very easy."

technique, odddimensional Epstein zeta functions and Casimir energy of massless scalar fields",
submitted to J. Physics A
[abstract:] "Quantum fluctuations of massless scalar fields represented by quantum fluctuations
of the quasiparticle vacuum in a zerotemperature dilute BoseEinstein condensate may well
provide the first experimental arena for measuring the Casimir force of a field other than the
electromagnetic field. This would constitute a real Casimir force measurement  due to quantum
fluctuations  in contrast to thermal fluctuation effects. We develop a multidimensional cutoff
technique for calculating the Casimir energy of massless scalar fields in ddimensional
rectangular spaces with q large dimensions and dq dimensions of length L and generalize
the technique to arbitrary lengths. We explicitly evaluate the multidimensional remainder and
express it in a form that converges exponentially fast. Together with the compact analytical
formulas we derive, the numerical results are exact and easy to obtain. Most importantly, we
show that the division between analytical and remainder is not arbitrary but has a natural
physical interpretation. The analytical part can be viewed as the sum of individual parallel
plate energies and the remainder as an interaction energy. In a separate procedure, via results
from number theory, we express some odddimensional homogeneous Epstein zeta functions as
products of onedimensional sums plus a tiny remainder and calculate from them the Casimir
energy via zeta function regularization."

"Supersymmetry and
electroweak breaking with large and small extra dimensions", Nucl. Phys. B
617 (2001) 71–100
[abstract:] "We consider the problem of supersymmetry and electroweak breaking in a
5d theory compactified on an $S^{1}/Z_{2}$ orbifold, where the extra dimension may be
large or small. We consider the case of a supersymmetry breaking 4d brane located at
one of the orbifold fixed points with the Standard Model gauge sector, third family
and Higgs fields in the 5d bulk, and the first two families on a parallel 4d matter
brane located at the other fixed point. We compute the KaluzaKlein mass spectrum in
this theory using a matrix technique which allows us to interpolate between large and
small extra dimensions. We also consider the problem of electroweak symmetry breaking
in this theory and localize the Yukawa couplings on the 4d matter brane spatially
separated from the brane where supersymmetry is broken. We calculate the 1loop effective
potential using a zetafunction regularization technique, and find that the dominant
top and stop contributions are separately finite. Using this result we find consistent
electroweak symmetry breaking for a compactification scale {$ 1/R \approx 830$ GeV} and
a lightest Higgs boson mass $m_{h} \approx 170$ GeV."

and threeloop amplitudes in covariant loop calculus", Nuclear Physics B 313 (1989) 432–446
[abstract:] "We study two and threeloop vacuum amplitudes for the closed bosonic string. We compare
two sets of expressions for the corresponding density on moduli space. One is based on the covariant
reggeon loop calculus (where modular invariance is not manifest). The other is based on analytic geometry.
We want to prove identity between the two sets of expressions. Quite apart from demonstrating modular
invariance of the reggeon results, this would in itself be a remarkable mathematical feature. Identity is
established to 'high' order in some moduli and exactly in others. The expansions reveal an essentially
numbertheoretic structure. Agreement is found only by exploiting the connection between the four Jacobi

geometry (one loop is known to be okay). We establish identity to 'high' order in some moduli

hypergeometric functions of unit argument. In all other cases we derive multiple MellinBarnes representations

[abstract:] "We present the threeloop remainder function, which describes the scattering of six gluons in the maximallyhelicityviolating configuration in planar $N=4$ superYangMills theory, as a function of the three dual conformal cross ratios. The result can be expressed in terms of multiple Goncharov polylogarithms. We also employ a more restricted class of "hexagon functions" which have the correct branch cuts and certain other restrictions on their symbols. We classify all the hexagon functions through transcendental weight five, using the coproduct for their Hopf algebra iteratively, which amounts to a set of firstorder differential equations. The threeloop remainder function is a particular weightsix hexagon function, whose symbol was determined previously. The differential equations can be integrated numerically for generic values of the cross ratios, or analytically in certain kinematics limits, including the nearcollinear and multiRegge limits. These limits allow us to impose constraints from the operator product expansion and multiRegge factorization directly at the function level, and thereby to fix uniquely a set of Riemannzetavalued constants that could not be fixed at the level of the symbol. The nearcollinear limits agree precisely with recent predictions by Basso, Sever and Vieira based on integrability. The multiRegge limits agree with the factorization formula of Fadin and Lipatov, and determine three constants entering the impact factor at this order. We plot the threeloop remainder function for various slices of the Euclidean region of positive cross ratios, and compare it to the twoloop one. For large ranges of the cross ratios, the ratio of the threeloop to the twoloop remainder function is relatively constant, and close to $7$."

superstring theory is developed. This is applied to determine coefficients up to order $s^6R^4$ (where $s$ is a Mandelstam invariant and $R^4$ the
linearized supercurvature), and partial results are obtained beyond that order. This involves integrating powers of the scalar propagator on a toroidal
worldsheet, as well as integrating over the modulus of the torus. At any given order in $s$ the coefficients of these terms are given by rational numbers
multiplying multiple zeta values (or EulerZagier sums) that, up to the order studied here, reduce to products of Riemann zeta values. We are careful
to disentangle the analytic pieces from logarithmic threshold terms, which involves a discussion of the conditions imposed by unitarity. We further
consider the compactification of the amplitude on a circle of radius $r$, which results in a plethora of terms that are powerbehaved in $r$. These
coefficients provide boundary `data' that must be matched by any nonperturbative expression for the lowenergy expansion of the fourgraviton
amplitude.

[abstract:] "Scattering amplitudes of superstring theory are strongly constrained by the requirement that they be invariant under dualities generated by discrete subgroups, $E_n(Z)$, of simplylaced Lie groups in the $E_n$ series ($n\leq 8$). In particular, expanding the foursupergraviton amplitude at low energy gives a series of higher derivative corrections to Einstein's theory, with coefficients that are automorphic functions with a rich dependence on the moduli. Boundary conditions supplied by string and supergravity perturbation theory, together with a chain of relations between successive groups in the $E_n$ series, constrain the constant terms of these coefficients in three distinct parabolic subgroups. Using this information we are able to determine the expressions for the first two higher derivative interactions (which are BPSprotected) in terms of specific Eisenstein series. Further, we determine key features of the coefficient of the third term in the low energy expansion of the foursupergraviton amplitude (which is also BPSprotected) in the $E_8$ case. This is an automorphic function that satisfies an inhomogeneous Laplace equation and has constant terms in certain parabolic subgroups that contain information about all the preceding terms."

[abstract:] "The twoloop Type II superstring correction to supergravity at order $D^6 R^4$ is derived from the genustwo superstring 4point function of massless NSNS states. We show that this correction is proportional to the integral over moduli space of a modular invariant introduced recently by Zhang and Kawazumi in number theory and related to the Faltings deltainvariant studied for genustwo by Bost. Furthermore, the structure of twoloop superstring corrections at higher order in the low energy expansion leads to higher invariants, which naturally generalize ZhangKawazumi invariant at genus two. An explicit formula is derived for the unique higher invariant associated with order $D^8 R^4$. In an attempt to compare the prediction for the $D^6 R^4$ correction from superstring perturbation theory with the one produced by Sduality and supersymmetry of Type IIB, various reformulations of the invariant are given. This comparison with string theory leads to a predicted value for the integral of the invariant over the moduli space of genustwo surfaces."

[abstract:] "We provide an introduction to the theory of Eisenstein series and automorphic forms on real simple Lie groups $G$, emphasising the role of representation theory. It is useful to take a slightly wider view and define all objects over the (rational) adeles $A$, thereby also paving the way for connections to number theory, representation theory and the Langlands program. Most of the results we present are already scattered throughout the mathematics literature but our exposition collects them together and is driven by examples. Many interesting aspects of these functions are hidden in their Fourier coefficients with respect to unipotent subgroups and a large part of our focus is to explain and derive general theorems on these Fourier expansions. Specifically, we give complete proofs of Langlands' constant term formula for Eisenstein series on adelic groups $G(A)$ as well as the CasselmanShalika formula for the $p$adic spherical Whittaker vector associated to unramified automorphic representations of $G(Q_p)$. Somewhat surprisingly, all these results have natural interpretations as encoding physical effects in string theory. We therefore introduce also some basic concepts of string theory, aimed toward mathematicians, emphasising the role of automorphic forms. In addition, we explain how the classical theory of Hecke operators fits into the modern theory of automorphic representations of adelic groups, thereby providing a connection with some key elements in the Langlands program, such as the Langlands dual group $LG$ and automorphic $L$functions. Our treatise concludes with a detailed list of interesting open questions and pointers to additional topics where automorphic forms occur in string theory."

One can prove that 2functions with rational coefficients appear as building block of BPS generating functions in topological string theory. Using the Frobenius map we define 2functions with coefficients in algebraic number fields. We establish two results pertaining to these functions. First, we show that the class of 2functions is closed under the socalled framing operation (related to compositional inverse of power series). Second, we show that 2functions arise naturally in geometry as $q$expansion of the truncated normal function associated with an algebraic cycle extending a degenerating family of CalabiYau 3folds."

on them. We argue that the relation between the dessins and SeibergWitten theory is useful because gauge theory criteria used to distinguish branches of $N=1$
vacua can lead to mathematical invariants that help to distinguish dessins belonging to different Galois orbits. For instance, we show that the confinement index
defined in hepth/0301006 is a Galois invariant. We further make some conjectures on the relation between

line Real $z = 1/2$ (but inside the critical strip), these putative zeros do not correspond to any poles of
the bosonic open string scattering (Veneziano) amplitude $A(s,t,u)$. The physical relevance of
tachyonicresonances/tachyoniccondensates in bosonic string theory, establishes an important connection between string

"Statistical mechanics of 2+1 gravity from Riemann zeta function and
Alexander polynomial: Exact results"
"In the recent publication (Journal of Geometry and Physics,
33 (2000) 23102) we demonstrated that dynamics of 2+1 gravity
can be described in terms of train tracks. Train tracks were
introduced by Thurston in connection with description of dynamics of
surface automorphisms. In this work we provide an example of
utilization of general formalism developed earlier. The complete exact
solution of the model problem describing equilibrium dynamics of
train tracks on the punctured torus is obtained. Being guided by
similarities between the dynamics of 2d liquid crystals and 2+1
gravity the partition function for gravity is mapped into that for
the Farey spin chain. The Farey spin chain partition function,
fortunately, is known exactly and has been thoroughly investigated
recently. Accordingly, the transition between the pseudoAnosov and
the periodic dynamic regime (in Thurston's terminology) in the case
of gravity is being reinterpreted in terms of phase transitions in the
Farey spin chain whose partition function is just a ratio of two
Riemann zeta functions. The mapping into the spin chain is
facilitated by recognition of a special role of the Alexander
polynomial for knots/links in study of dynamics of self
homeomorphisms of surfaces. At the end of paper, using some facts
from the theory of arithmetic hyperbolic 3manifolds (initiated by
Bianchi in 1892), we develop systematic extension of the obtained
results to noncompact Riemannian surfaces of higher genus. Some of
the obtained results are also useful for 3+1 gravity. In particular,
using the theorem of Margulis, we provide new reasons for the black
hole existence in the Universe: black holes make our Universe
arithmetic. That is the discrete Lie groups of motion are arithmetic."

G. Dattoli, M. Del Franco, "The Euler legacy to modern physics" (preprint 09/2010)
[abstract:] "Particular families of special functions, conceived as purely mathematical devices between the end of XVIII and the beginning of XIX centuries, have played a crucial role in the development of many aspects of modern Physics. This is indeed the case of the Euler gamma function, which has been one of the key elements paving the way to string theories,
furthermore the Euler–Riemann Zeta function has played a decisive role in the development of renormalization theories. The ideas of Euler and later those of Riemann, Ramanujan and of other, less popular, mathematicians have therefore provided the
mathematical apparatus ideally suited to explore, and eventually solve, problems of fundamental importance in modern Physics. The mathematical foundations of the theory of renormalization trace back to the work on divergent series by Euler and by mathematicians of two centuries ago. Feynman, Dyson, Schwinger... rediscovered most of these mathematical "curiosities" and were able to develop a new and powerful way of looking at physical phenomena."
In Section 2.3 of Bernard Julia's seminal 1990 paper "Statistical
theory of numbers", the author turns briefly from multiplicative
to additive number theory, in particular to generating functionals associated with
integer partition problems. He relates these to the Veneziano open string model, the tachyon mode, and the
phenomenon of "bosonization" which is discussed elsewhere in the paper.
L. Brekke and P. Freund, "padic numbers in physics", Physics Reports 233, (1993) 1–66
This is a review article related to the achievements in application
of padic numbers to string theory, quantum field theory and
quantum mechanics during the period 19871992. The contribution of
Freund and his collaborators is emphasised.
Here is an excerpt from pp.61–62:
"String theory, the candidate "theory of everything" is expected to
raise fundamental issues both at the level of physics and at the level
of mathematics. The old issue of the nature of continuity in physics
naturally leads to the consideration of padic strings. It is
remarkable that these very simple alternate topologies have not
appeared earlier in physics (ultrametrics have appeared [62]). Yet,
even now it would not be reasonable to actually select a prime and
claim this to be the phenomenologically preferred prime which
"underlies" physics. As we have seen, such a preferred prime could lead
to serious causality problems. But if none of the primes is to be
preferred, then why select a priori the prime at infinity, and deal
exclusively with real numbers? A more "evenhanded" procedure would
envision dealing with all primes at the same time. This naturally leads
to adelic theories. We have seen that this point of view immediately
yields the remarkable adelic product formulae. Could it be that the
adelic string is the "real thing"? This question has been raised by
Manin [41] in the following (somewhat paraphrased) form. Supposing that
the true physics is adelic, then why can we always assume it to be
archimedean, grounded in the real numbers? Maybe this is on account of
some experimental limitations, e.g. low energy. Could it be that once
these limitations get lifted and we reach very high (Planck) energies,
the full adelic structure of the string will reveal itself? This is an
interesting possibility.
Another possibility is that the true theory is archimedean, but that
on account of the product formulae, one could alternatively conceive of
the theory as an Euler product over all padic theories. As we saw,
each such theory puts the strings' world sheet on a Bethe lattice. What
the adelic formulae then tell us is that we should not opt for a
particular Bethe lattice as the discretization of the world sheet, but
rather study absolutely all of them. The cumulative understanding of
all these discretizations is tantamount to understanding the ordinary
archimedean string. Of course, each of these discretizations is far
simpler than the ordinary string.
On the other hand, there is the padicsquantum group connection,
which places the ordinary and all the padic strings at certain special
points in a continuum of theories. It is an important problem to assess
the theoretical consistency of all these "quantum" strings and the
phenomenological possibilities offered by them."

The direct search of the exact solutions of the Einstein equation even in this simple metric case is sometime a hard job.

In this work, we establish the relationship the Einstein equation with two other famous equations namely the Ramanujan equation and the Chazy equation. Both these two equations play an imporatant role in the number theory. Using the known solutions of the Ramanujan and Chazy equations, we find the corresponding solutions of the Einstein equation."

[from publisher's description:] "In this book, the author proposes a new approach to understand and possibly
solve the Riemann Hypothesis. His reformulation builds upon earlier (joint) work on complex fractal dimensions
and the vibrations of fractal strings, combined with string theory and noncommutative geometry. Accordingly, it
relies on the new notion of a fractal membrane or quantized fractal string, along with the modular flow on the
associated modui space of fractal membranes. Conjecturally, under the action of the modular flow, the spacetime
geometries become increasingly symmetric and crystallike, hence, arithmetic. Correspondingly, the zeros of the
associated zeta functions eventually condense onto the critical line, towards which they are attracted, thereby
explaining why the Riemann Hypothesis must be true.
Written with a diverse audience in mind, this unique book is suitable for graduate students, experts and
nonexperts alike, with an interest in number theory, analysis, dynamical systems, arithmetic, fractal or
noncommutative geometry, and mathematical and mathematical or theoretical physics."

We prove a link between the error estimate and the Riemann hypothesis. Further, we prove $\pmb{\Gamma}_{g  r}$ modularity of the function obtained by iterating the unipotent average process $r$ times. This shows uniformization of modular integrals of automorphic functions via unipotent flows."

[abstract:] "We revisit the numbertheory dark matter scenario where one of the light chiral fermions required by the anomaly cancellation conditions of $U(1)_{BL}$ explains dark matter. Focusing on some of the integer BL charge assignments, we explore a new region of the parameter space where there appear two light fermions and the heavier one becomes a dark matter of mass O(10)keV or O(10)MeV. The dark matter radiatively decays into neutrino and photon, which can explain the tantalizing hint of the 3.55keV Xray line excess. Interestingly, the other light fermion can erase the AdS vacuum around the neutrino mass scale in a compactification of the standard model to 3D. This will make the standard model consistent with the AdSWGC statement that stable nonsupersymmetric AdS vacua should be absent."

The symmetries depend sensitively on the arithmetic properties (e.g. prime factorization) of the matrix of Chern–Simons levels, revealing interesting connections with number theory. We give a complete characterization of the symmetries of abelian topological field theories and along the way find many theories that are nontrivially timereversal invariant by virtue of a quantum symmetry, including $U(1)_k$ Chern–Simons theory and $(\mathbb{Z}_k)_l$ gauge theories. For example, we prove that $U(1)_k$ Chern–Simons theory is timereversal invariant if and only if $1$ is a quadratic residue modulo $k$, which happens if and only if all the prime factors of $k$ are Pythagorean (i.e., of the form $4n+1$), or Pythagorean with a single additional factor of $2$. Many distinct nonabelian finite symmetry groups are found.
Conference: "Modular
Forms and String Duality", Banff International Research Station, June 3–8, 2006
"Physical duality symmetries relate special limits of the various consistent string theories (Types I, II, Heterotic
string and their cousins, including Ftheory) one to another. By comparing the mathematical descriptions of these theories,
one reveals often quite deep and unexpected mathematical conjectures. The best known string duality to mathematicians, Type
IIA/IIB duality also called mirror symmetry, has inspired many new developments in algebraic and arithmetic geometry,
number theory, toric geometry, Riemann surface theory, and infinite dimensional Lie algebras. Other string dualities such
as Heterotic/Type II duality and FTheory/Heterotic string duality have also, more recently, led to series of mathematical
conjectures, many involving elliptic curves, K3 surfaces, and modular forms. Modular forms and quasimodular forms play a
central role in mirror symmetry, in particular, as generating functions counting the number of curves on CalabiYau manifolds
and describing GromovWitten invariants. This has led to a realization that time is ripe to assess the role of number theory,
in particular, that of modular forms, in mirror symmetry and string dualities in general.
One of the principal goals of this workshop is to look at modular and quasimodular forms, congruence zetafunctions, Galois
representations, and Lseries for dual families of CalabiYau varieties with the aim of interpreting duality symmetries in
terms of arithmetic invariants associated to the varieties in question. Over the last decades, a great deal of work has been
done on these problems. In particular it appears that we need to modify the classical theories of Galois representations (in
particular, the question of modularity) and modular forms, among others, for families of CalabiYau varieties in order to
accommodate "quantum corrections"."

[abstract:] "According to quantum mechanics, the properties of an atom can be calculated easily if we known the eigenfunctions
and eigenvalues of quantum states in which the atom can be found. The eigenfunctions depend, in general, by the coordinates of all
the electrons. However, a diagram effective and enough in many cases, we can get considering the individual eigenfunctions for
individual electrons, imagining that each of them is isolated in an appropriate potential field that represent the action of the
nucleus and of other electrons. From these individual eigenfunctions we can to obtain the eigenfunction of the quantum state of
the atom, forming the antisymmetrical products of eigenfunctions of the individual quantum states involved in the configuration
considered. The problem, with this diagram, is the calculation of the eigenfunctions and eigenvalues of individual electrons of
each atomic species. To solve this problem we must find solutions to the Schroedinger's equation where explicitly there is the
potential acting on the electron in question, due to the action of the nucleus and of all the other electrons of the atom. To
research of potential it is possible proceed with varying degrees of approximation: a first degree is obtained by the statistical
method of ThomasFermi in which electrons are considered as a degenerate gas in balance as a result of nuclear attraction. This
method has the advantage of a great simplicity as that, through a single function numerically calculated once and for all, it is
possible to represent the behaviour of all atoms. In this work (Sections 1 and 2) we give the preference to the statistical method,
because in any case it provides the basis for more approximate numerical calculations. Furthermore, we describe the mathematical

[abstract:] "There is a connection between string theory and the Riemann's zeta function: this is an interesting way, because the zeta is related
to prime numbers and we have seen on many occasions how nature likes to express himself through perfect laws or mathematical models. In [6] the authors
showed all the mathematical and theoretical aspects related to the Riemann's zeta, while in [9] showed the links of certain formulas of number theory
with the golden section and other areas such as string theory. The authors have proposed a solution of the Riemann hypothesis (RH) and the conjecture
on the multiplicity of nontrivial zeros, showing that they are simple zeros [7][8]. Not least the situation that certain stable energy levels of atoms
could be associated with nontrivial zeros of the Riemann's zeta. In [6] for example has been shown the binding of the Riemann zeta and its nontrivial
zeros with quantum physics through the Law of MontgomeryOdlyzko. The law of MontgomeryOdlyzko says that "the distribution of the spacing between
successive nontrivial zeros of the Riemann zeta function (normalized) is identical in terms of statistical distribution of spacing of eigenvalues in
an GUE operator", which also represent dynamical systems of subatomic particles! In [10] [11] have proposed hypotheses equivalent RH, in [12] [13] the

Here is an excerpt from a posting by on the sci.physics newsgroup (02/98)
by Dan Piponi:
"In (bosonic) string theory via the operator formalism you find an
infinite looking zero point energy just like in QED except that you get
a sum that looks like:
1+2+3+4+...
Now the naive thing to do is the same: subtract off this zero point
energy. However later on you get into complications. In fact (if I
remember correctly) you must replace this infinity with 1/12 (of all
things!) to keep things consistent.
Now it turns out there is a nice mathematical kludge that allows you to
see 1+2+3+4+... as equalling 1/12. What you do is rewrite it as
1+2^{n} +3^{n} +...
This is the Riemann Zeta function. This converges for large n but can be
analytically continued to n = 1, even though the series doesn't converge
there. Zeta(1) is 1/12. So in some bizarre sense 1+2+3+4+... really is
1/12.
But even more amazingly is that you can get the 1/12 by a completely
different route  using the path integral formalism rather than the
operator formalism. This 1/12 is tied up in a deep way with the
geometry of string theory so it's a lot more than simply a trick to keep
the numbers finite.
However I don't know if the equivalent operation in QED is tied up with
the same kind of interesting geometry."
C. Clark, "Math formula gives new glimpse into the magical mind of Ramanujan" (phys.org, 12/2012)
[excerpt:] "The result is a formula for mock modular forms that may prove useful to physicists who study black holes. The work, which Ono recently presented at the Ramanujan 125 conference at the University of Florida, also solves one of the greatest puzzles left behind by the enigmatic Indian genius.
"No one was talking about black holes back in the 1920s when Ramanujan first came up with mock modular forms, and yet, his work may unlock secrets about them," [Ken] Ono says. Expansion of modular forms is one of the fundamental tools for computing the entropy of a modular black hole. Some black holes, however, are not modular, but the new formula based on Ramanujan's vision may allow physicists to compute their entropy as though they were."
J.F.R. Duncan, M.J. Griffin and K. Ono, "Moonshine" (preprint 11/2014)
[abstract:] "Monstrous moonshine relates distinguished modular functions to the representation theory of the monster. The celebrated observations that 196884 = 1 + 196883 and 21493760 = 1+196883+21296876, etc., illustrate the case of the modular function j  744, whose coefficients turn out to be sums of the dimensions of the 194 irreducible representations of the monster. Such formulas are dictated by the structure of the graded monstrous moonshine modules. Recent works in moonshine suggest deep relations between number theory and physics. Number theoretic Kloosterman sums have reappeared in quantum gravity, and mock modular forms have emerged as candidates for the computation of black hole degeneracies. This paper is a survey of past and present research on moonshine. We also obtain exact formulas for the multiplicities of the irreducible components of the moonshine modules. These formulas imply that such multiplicities are asymptotically proportional to dimensions."
