On the average size of the eigenvalues of the Hecke operators

Number Theory 2025-02-18 v2

Abstract

We determine the average size of the eigenvalues of the Hecke operators acting on the cuspidal modular forms space Sk(Γ0(N))S_k(\Gamma_0(N)) in both the vertical and the horizontal perspective. The "average size" is measured via the quadratic mean.
