"Over the years striking analogies have been observed between the Riemann zeta-function and other zeta- or L-functions. While these functions are seemingly independent of each other, there is growing evidence that they are all somehow connected in a way that we do not fully understand. In any event, trying to understand, or at least classify, all of the objects which we believe satisfy the Riemann hypothesis is a reasonable thing to do."

J. Brian Conrey, "The Riemann Hypothesis", Notices of the AMS (March, 2003) p.347

"In this essay I will give a strictly subjective selection of different types of zeta functions. Instead of providing a complete list, I will rather try to give the central concepts and ideas underlying the theory...

Whenever entities are counted with some mathematical structure on them it is likely that a zeta function can be set up and often enough it will extend to a meromorphic function. Zeta functions show up in all areas of mathematics and they encode properties of the counted objects which are well hidden and hard to come by otherwise. They easily give fuel for bold new conjectures and thus drive on mathematical research. It is a fairly safe assertion to say that zeta functions of various kinds will stay in the focus of mathematical attention for times to come. "

A. Deitmar, "Panorama of zeta functions" (preprint 10/02)

"Some decades ago I made - somewhat in jest - the suggestion that one should get accepted a non-proliferation treaty of zeta functions. There was becoming such an overwhelming variety of these objects."

Atle Selberg, quoted in K. Sabbagh, Dr. Riemann's Zeros (Atlantic, 2002)

"In concentrating exclusively on the study of the [Riemann] zeta function and its relation to the prime number theorem, this book ignores one of the most fruitful areas of development of Riemann's work, namely, number theory. The use of functions like the zeta function in number theory was a major feature of the work of Dirichlet- both in his L-series and in his formula for the class number of a quadratic number field - many years before Riemann's paper appeared, and the use of such functions has been a prominent theme in number theory ever since. Riemann's contributions in this area were primarily function-theoretic, not number-theoretic, and consisted of focussing attention on the functions as functions of a complex variable, on the possibility of their satisfying a functional equation under s <--> 1 - s, and on the importance of the location of their complex zeros. A few of the most important names in the subsequent study of these number theoretic functions are those of Dedekind, Hilbert, Hecke, Artin, Weil, and Tate.

Ignorance prevents me from entering into a discussion of these functions and what is known about them. However, it seems that they provide some of the best reasons for believing that the Riemann hypothesis is true - for believing, in other words, that there is a profound and as yet uncomprehended number-theoretic phenomenon, one facet of which is that the roots all lie on Re[s] = 1/2. In particular, there is a 'zeta function' associated in a natural number-theoretic way to any function field over a finite field, and Weil has shown that the analog of the Riemann hypothesis is true for such 'zeta functions'"

H.M. Edwards, from Riemann's Zeta Function (Academic Press, 1974) p. 298

Some useful discussion of the very fundamental question "what is a zeta function?" took place at the 2002 conference on zeta functions and associated Riemann Hypotheses in New York.

As M. Huxley puts it: "We know one when we see one."

J. Baez's This Weeks Finds in Mathematical Physics Week 216 contains some useful discussion about various types of zeta functions. week 217 includes very helpful discussion of the Riemann Hypothesis, Extended Riemann Hypothesis, Grand Riemann Hypothesis, Weil Conjectures, Langlands Programme, the functional equations of zeta and L-functions, modularity of theta functions, etc. week 218 follows this up, framing certain issues concerning the bewildering array of zeta and L-functions in terms of category theory.

P.E. Cartier, B. Julia, P. Moussa and P. Vanhove (eds.), Frontiers in Number Theory, Physics, and Geometry: On Random Matrices, Zeta Functions, and Dynamical Systems (Springer, 2006)

Probably the best overall view of zeta functions as a general phenomenon appears in the Mathematical Society of Japan's Encyclopedic Dictionary of Mathematics (pp. 1372-1392 of the English edition published by MIT Press in 1977)

The introductory section informs us:

"Since the 19th century, many special functions called zeta functions have been defined and investigated. The four main problems concerning zeta functions are:

(1) Creation of new zeta functions.

(2) Investigation of the properties of zeta functions. Generally, zeta functions have the following four properties in common: (i) They are meromorphic on the whole complex plane; (ii) they have Dirichlet series expansions; (iii) they have Euler products expansions; and (iv) they satisfy certain functional equations. Also it is an important problem to find the poles, residues, and zeros of zeta functions.

(3) Application to number theory, in particular to the theory of decomposition of prime ideals in finite extensions of algebraic number fields. (4) Study of the relations between different zeta functions.

Most of the functions called zeta-functions or L-functions have the four properties of problem (2). The following is a classification of the important types of zeta functions that are already known, which will be discussed later in this article:

(1) The zeta and L-functions of algebraic number fields: the Riemann zeta function, Dirichlet L-functions (study of these functions gave impetus to the theory of zeta functions), Dedekind zeta functions, Hecke L-functions, Hecke L-functions with Grossencharakters, Artin L-functions, and Weil L-functions.

(2) The p-adic L-functions related to the works of H.W. Leopoldt, T. Kubota, K. Iwasaw, etc.

(3) The zeta functions of quadratic forms: Epstein zeta functions, zeta functions of indefinite quadratic forms (C.L. Siegel), etc.

(4) The zeta and L-functions of simple algebras: Hey zeta functions and the zeta functions given by R. Godement, T. Tamagawa, etc.

(5) The zeta functions associated with Hecke operators, related to the work of E. Hecke, M. Eichler, G. Shimura, etc.

(6) The congruence zeta and L-functions attached to algebraic varietites defined over finite fields (E. Artin, F.K. Schmidt, A. Weil); Hasse zeta functions attached to the algebraic varietites defined over algebraic number fields.

(7) The zeta functions attached to discontinuous groups: Selberg zeta functions, the Eisenstein series defined by A. Selberg, Godement, and I.M. Gel'fand, etc.

(8) Y. Ihara's zeta function related to non-Abelian class field theory over a function field over a finite field.

(9) zeta functions associated with prehomogeneous vector spaces."

Dedekind zeta functions

WWN notes on Dedekind zeta functions (part of a work-in-progress)

From J.T. Tate, "Fourier analysis in number fields and Hecke's zeta-functions" [1950 Princeton Ph.D. thesis, reproduced as Chapter 15 of Algebraic Number Theory by J.W.S. Cassels and A. Fröhlich (Academic Press, 1967)]:

"Hecke was the first to prove that the Dedekind zeta-function of any algebraic number field has an analytic continuation over the whole plane and satisfies a simple functional equation. He soon realized that this method would work, not only for the Dedekind zeta-function and L-series, but also for a zeta-function formed with a new type of ideal character which, for principal ideals depends not only on the residue class of the number modulo the "conductor", but also on the position of the conjugates of the number in the complex field. Overcoming rather extraordinary technical complications, he showed (1918 and 1920) that these "Hecke" zeta-functions satisfied the same type of functional equation as the Dedekind zeta-function, but with a much more complicated factor."

P. Cohen, Dedekind zeta functions and quantum statistical mechanics

[abstract] "In this article we construct a C*-dynamical system with partition function the Dedekind zeta function of a given number field and with a phase transition at the pole of this zeta function which detects a breaking of symmetry with respect to a natural symmetry group. This extends work of Bost-Connes and Harari-Leichtnam."

Elizalde zeta functions

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. Although I don't think they've appeared in print under this name, it seems an appropriate one to give them. 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 Chowla-Selberg formula.

[Jacobi zeta function]

M. Somos points out "...not at all like the other zeta functions mentioned. It is an elliptic function with double quasi-periodicity. There is nothing like the non-trivial zeros a la Riemann Hypothesis...note that it is just a historical accident that it was called a zeta function and has nothing to do with the rest...As a curiosity, the Jacobi theta function is involved with the functional equation of the Riemann zeta function via the Mellin transform. However, this is as close as it gets regarding Jacobi and his elliptic functions."

Chapter 10 covers the Trace Formula, and on p.154 we find a helpful note about Selberg zeta functions:

"If you will, the Selberg zeta-function satisfies an analogue of the Riemann hypothesis. However, the analogy with the Riemann zeta-function is superficial. First of all, the Selberg zeta function has no natural development into Dirichlet series. Furthermore, the functional equation...resists any decent interpretation as a kind of Poisson summation principle. Nevertheless, modern studies of Z(s) have caused a lot of excitement in mathematical physics (see [Sa1]). At least, one may say that the dream of Hilbert and Pólya of connecting the zeros of a zeta-function with eigenvalues of a self-adjoint operator is a reality in the context of Z(s)."
