Moments of ideal class counting functions

Abstract

We consider the counting function of ideals in a given ideal class of a number field of degree dd. This describes, at least conjecturally, the Fourier coefficients of an automorphic form on GL(d)\text{GL}(d), typically not a Hecke eigenform and not cuspidal. We compute its moments, and also investigate the moments of the corresponding cuspidal projection.
