Arithmetic properties of the Herglotz function

  title={Arithmetic properties of the Herglotz function},
  author={Danylo V. Radchenko and Don Zagier},
In this paper we study two functions F (x) and J(x), originally found by Herglotz in 1923 and later rediscovered and used by one of the authors in connection with the Kronecker limit formula for real quadratic fields. We discuss many interesting properties of these functions, including special values at rational or quadratic irrational arguments as rational linear combinations of dilogarithms and products of logarithms, functional equations coming from Hecke operators, and connections with…

Extended higher Herglotz functions I. Functional equations

Abstract. In 1975, Don Zagier obtained a new version of the Kronecker limit formula for a real quadratic field which involved an interesting function F (x) which is now known as the Herglotz

A Kronecker limit formula for indefinite zeta functions

Indefinite zeta function are Mellin transforms of indefinite theta function (a la Zwegers) and specialise to differenced ray class zeta functions of real quadratic fields. We prove a Kronecker limit

Explicit transformations of certain Lambert series

An exact transformation, which we call the master identity , is obtained for the first time for the series $$\sum _{n=1}^{\infty }\sigma _{a}(n)e^{-ny}$$ ∑ n = 1 ∞ σ a ( n ) e - n y for $$a\in

Extended Higher Herglotz function \textup{II}

. Very recently, Radchenko and Zagier revived the theory of Herglotz functions. The main goal of the article is to show that one of the formulas on page 220 of Ramanujan’s Lost Notebook actually



Higher Kronecker “limit” formulas for real quadratic fields

Abstract For every integer k ≧ 2 we introduce an analytic function of a positive real variable and give a universal formula expressing the values ζ(ℬ, k) of the zeta functions of narrow ideal classes

A generalization of the Chowla-Selberg formula and the zeta functions of quadratic orders

The purpose of this note is to present an identity which generalizes a formula of Chowla and Selberg on the periods o CM elliptic curves in connection with the zeta functions of imaginary quadratic

Hecke operators on weighted Dedekind symbols

Abstract Dedekind symbols generalize the classical Dedekind sums (symbols). The symbols are determined uniquely by their reciprocity laws up to an additive constant. There is a natural isomorphism

Curious and Exotic Identities for Bernoulli Numbers

Bernoulli numbers, which are ubiquitous in mathematics, typically appear either as the Taylor coefficients of x=tanx or else, very closely related to this, as special values of the Riemann zeta

A Kronecker limit formula for real quadratic fields

Then ((s, A) is (after analytic continuation) a meromorphic function of s with a simple pole at s = 1 as its only singularity. Moreover, the residue of ((s, A) at s = 1 is independent of the ideal

The author proves an algebraicity theorem for the periods of parabolic forms of any weight for the full modular group, gives explicit formulas for the coefficients of the forms, and constructs -adic

Genus character L ‐functions of quadratic orders and class numbers

An explicit form of genus character L ‐functions of quadratic orders is presented in full generality. As an application, we generalize a formula due to Hirzebruch and Zagier on the class number of
