A Kronecker Limit Formula for Totally Real Fields and Arithmetic Applications
نویسندگان
چکیده
We establish a Kronecker limit formula for the zeta function ζF (s,A) of a wide ideal class A of a totally real number field F of degree n. This formula relates the constant term in the Laurent expansion of ζF (s,A) at s = 1 to a toric integral of a SLn(Z)-invariant function logG(Z) along a Heegner cycle in the symmetric space of GLn(R). We give several applications of this formula to algebraic number theory, including a relative class number formula for H/F where H is the Hilbert class field of F , and an analog of Kronecker’s solution of Pell’s equation for totally real multiquadratic fields. We also use a well-known conjecture from transcendence theory on algebraic independence of logarithms of algebraic numbers to study the transcendence of the toric integral of logG(Z). Explicit examples are given for each of these results.

Asymptotic Properties of Dedekind Zeta Functions in Families of Number Fields
The main goal of this paper is to prove a formula that expresses the limit behaviour of Dedekind zeta functions for Re s > 1/2 in families of number fields, assuming that the Generalized Riemann Hypothesis holds. This result can be viewed as a generalization of the Brauer–Siegel theorem. As an application we obtain a limit formula for Euler–Kronecker constants in families of number fields.
متن کاملArithmetic Aspects of the Theta Correspondence and Periods of Modular Forms
We review some recent results on the arithmetic of the theta correspondence for certain symplectic-orthogonal dual pairs and some applications to periods and congruences of modular forms. We also propose an integral version of a conjecture on Petersson inner products of modular forms on quaternion algebras over totally real fields.
متن کاملCM values of automorphic Green functions on orthogonal groups over totally real fields
Generalizing work of Gross–Zagier and Schofer on singular moduli, we study the CM values of regularized theta lifts of harmonic Whittaker forms. We compute the archimedian part of the height pairing of arithmetic special divisors and CM cycles on Shimura varieties associated to quadratic spaces over an arbitrary totally real base field. As a special case, we obtain an explicit formula for the n...
متن کاملOn Kronecker limit formulas for real quadratic fields
Let ζ(s,C) be the partial zeta function attached to a ray class C of a real quadratic field. We study this zeta function at s = 1 and s = 0, combining some ideas and methods due to Zagier and Shintani. The main results are (1) a generalization of Zagier’s formula for the constant term of the Laurent expansion at s = 1, (2) some expressions for the value and the first derivative at s = 0, relate...
متن کاملTaylor Expansion of an Eisenstein Series
In this paper, we give an explicit formula for the first two terms of the Taylor expansion of a classical Eisenstein series of weight 2k + 1 for Γ0(q). Both the first term and the second term have interesting arithmetic interpretations. We apply the result to compute the central derivative of some Hecke L-functions. 0. Introduction. Consider the classical Eisenstein series ∑ γ∈Γ∞\ SL2(Z) Im(γτ)...
