abstract

  • 2015, The Author(s). We establish a Kronecker limit formula for the zeta function F(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 F(s,A) at s=1 to a toric integral of a SLn() -invariant function logG(Z) along a Heegner cycle in the symmetric space of GLn(). 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 Kroneckers solution of Pells 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.
