Estimates of triple products of automorphic functions II
arXiv:1202.4766
Abstract
We prove a sharp bound for the average value of the triple product of modular functions for the Hecke subgroup Î_0(N). Our result is an extension of the main result in {Bernstein&Reznikov-2004} to a fixed cuspidal representation of the adele group PGL(2,A).
