[abstract:] "Beurling defined a set, $P$, of generalized prime numbers as any non-decreasing unbounded sequence of real numbers which are greater than one. The multiplicative semi-group, $N$, generated by the elements of $P$ is called the associated set of generalized integers. The functions $Pi(x)$ and $N(x)$ are defined, respectively, as the number of generalized prime and integers less than or equal to $x$. This paper is concerned with deducing the behaviour of $Pi(x)$ from that of $N(x)$."

[abstract:] "Arne Beurling generalized the prime number theorem to the rather general situation when the role of primes are taken over by some arbitrary reals, and integers are simply the reals of the freely generated multiplicative subgroup of the primes given. If the "number of integers from $1$ to $x$" function takes the form $N(x) = x + O(x^a)$, with $a < 1$, then the corresponding Beurling zeta function has a meromorphic continuation to the half-plane to the right of $a$. Location of zeroes between the real part $= 1$ and real part = a lines are then crucial to the oscillation of the prime number formula, as is well-known in the classical case. The lecture describes how these relations can be established even in the generality of Beurling prime distribution."

[abstract:] "Two Beurling generalized number systems, both with $N(x)=kx+O(x^{1/2}}\exp\{c(\log\,x)^{2/3}\})$ and $k > 0$, are constructed. The associated zeta function of the first satisfies the RH and its prime counting function satisfies $\pi(x) = li(x) + O(x^{1/2})$. The associated zeta function of the second has infinitely many zeros on the curve $s = 1-1/log t$ and no zeros to the right of the curve and the Chebyshev function $\psi(x)$ of its primes satisfies $\limsup\, (\psi(x)-x)/(x\exp\{-2\sqrt{\log\,x}\})=2$ and $\liminf\, (\psi(x)-x)/(x\exp\{-2\sqrt{\log\,x}\})=-2$. A sharpened form of the Diamond-Montgomery-Vorhauer random approximation and elements of analytic number theory are used in the construction."




The only use of Beurling's generalisation by a physicist of which I am aware:

B. Julia, "Thermodynamic limit in number theory: Riemann-Beurling gases" Physica A 203 (1994) 425-436.

"We study the grand canonical version of a solved statistical model, the Riemann gas: a collection of bosonic oscillators with energies the logarithms of the prime numbers. The introduction of a chemical potential $\mu$ amounts to multiply each prime by $e^{\mu}$, the corresponding gases could be called Beurling gases because they are defined by the choice of appropriate generalized primes when considered as canonical ensembles; one finds generalized Hagedorn singularities in the temperature. The discrete spectrum can be treated as continuous in its high energy region; this approximation allows us to study the high energy level density and is applied to Beurling gases. It is expected to be accurate for the high temperature behaviour. One model (the logarithmic gases) will be studied in more detail, it corresponds to the choice of all the integers strictly larger than one as Beurling primes; we give an explicit formula for its grand canonical thermodynamic potential $F - \mu N$ in terms of a hypergeometric function and check the approximation on the Hagedorn phenomenon. Related physical situations include string theories and quark deconfinement where one needs a better understanding of the nature of the Hagedorn transitions."




A set of Beurling generalised integers has the Delone property if the gaps between succesive members are bounded above and below. This was introduced by the Russian crystallographer and number theorist B.N. Delone in 1937, motivated by the question of whether the crystal-like nature of Z+ is relevant to the (presumed) truth of Riemann hypothesis, according to the following:

This was brought to my attention by:

J. Lagarias, "Beurling generalized integers with the Delone property", Forum Math. 11 (1999) 295-312




T.W. Hilberdink and M.L. Lapidus, "Beurling zeta functions, generalised primes, and fractal membranes" (preprint 08/04)

Here is an excerpt from the introductory section, which refers to Lapidus's emerging idea of a (noncommutative) flow of Beurling g-prime systems.






H. Delille, who in 2004 began making and retracting claims that he had a proof of the Riemann hypothesis, provided this summary of his work, which involves the analytic continuation of Beurling zeta functions (August 2004).



In discussion with H. Diamond:

After seeing the original "prime evolution" notes, Martin Huxley contacted me to point out that I had re-invented the basic idea of Beurling's construction. I then contacted Harold Diamond who appeared to be one of the leading experts in this field. Diamond examined the notes and made the following comments:

"Prof. Huxley is correct: this topic lies in the area of Beurling generalized number theory. The essence of this theory is that if a sequence of g-integers is generated by a sequence of g-primes, and if one of the sequences is distributed sufficiently like its classical counterpart, then so too is the other."

[in reference to my remarks on the equal spacing of the integers:]

"Equally spaced. I believe that the Riemann Hypothesis will not be settled until methods have been developed which make effective use of the equal spacing of integers. Note that the functional equation of the Riemann zeta function does have this information encoded into it."

I later asked him to elaborate on this intriguing prediction, and received the following reply:

"The functional equation of the Riemann zeta function does contain information about the equal spacing of the integers, but it is very subtle. It shows itself in a few ways:

1) If one requires only an asymptotic law for the integer counting function of the form N(x) = x + O(1), one could make examples in which the associated generalized zeta function

had a natural boundary on the imaginary axis, i.e. the zeta function could not be continued further to the left, while the Riemann zeta function is continuable to the entire complex plane (except for the pole point s = 1).

2) If you extend the 1/2 plane of convergence of the Riemann zeta function by the Euler-Maclaurin summation formula, the good spacing of the integers allows you to keep the process going ad infinitum.

3) If you extend the Riemann zeta function to the complex plane by use of the functional equation, the proofs of the functional equation all contain as an element the good spacing of the integers.

The reason for the claim that equal spacing of integers is likely to be essential for a proof of the Riemann hypothesis is this: there are quite simple Beurling-theory examples of nice counting functions N(x) for which such a good approximation as N(x) = x + O(1) exists, but for which the zeta function has zeros off the line Re s = 1/2. The examples have proper multiplicative structure, the log of the zeta function is of a suitable type, and there is good approximability of N(x) by x, but they lack additive structure."

[in reference to my speculations on the necessary conditions for g-integers to have asymptotic density 1:]

"There is quite a bit known about g-integers having asymptotic density 1. Roughly speaking, in addition to the g-primes having to be distributed rather like the usual ones, an additional condition is needed to cause the density be exactly 1.

A trivial remark: the set of generalized integers consisting of all odd numbers (the prime 2 has been killed) also has the property of being equally spaced. It says that the sequence of standard primes is not the only one that generates equally spaced integers. Note that in this example we have density 1/2.

Brief commments on my questions about modified zeta functions. First, this is very appropriate for studying such problems. Questions of half planes of convergence of the zeta function and behavior of the zeta function at the point 1 are easily answered in terms of the rate of growth of the integer counting function. Questions of an extension of the generalized zeta function to - {1} and its properties in the newly gained territory appear to be very difficult. It is not obvious how zeros of the zeta function move around under perturbations of the primes. If you start with the classical primes, and do your permutations one prime at a time, you will not affect the classical zeta function zeros, but you will induce a bunch of zeros and poles of the new zeta function on the imaginary axis. If you are permuting everything at the same time, I don't have a clue about the behavior of the zeros.

Relating to my point about continuous prime distributions in section 3.6, in some sense Dirac measure at the point 1 + Lebesgue measure on represents another distinguished limiting configuration that is related to the counting measure of positive integers and is generated by a measure whose integral is close to . I have exploited this relation in several of my articles."

I asked Professor Diamond to explain what he meant by "distinguished limiting configuration", and got the following reply:

"This is a bit queasy, but here goes.

Imagine that we set out to transmogrify the primes into a continuous mass distribution by successively cashing in classical primes and replacing them with a couple of nearby numbers, each with reduced multiplicity. For example, the factor (1 - 2-s)-1 in the product form of the Riemann zeta function could be replaced by a couple of factors of the form (1 - aj-s)-b_j for suitable numbers aj around 2 and suitable (small!) exponents bj. The notion of `suitable' is to keep the counting function N(x) pretty close to x. The process is repeated ad infinitum, at each stage causing each of the 'primes' to be replaced by a bunch of numbers each with much lower multiplicity. The distribution that I discussed, with counting measure Dirac measure at the point 1 + Lebesgue measure on has integral that is exactly x, at least for x > 1 and moreover, the associated zeta function has a logarithm which is very analogous to the log of the Riemann zeta function.

I have written about this stuff in some of the Beurling articles."
