Coefficient Bounds for Level 2 Cusp Forms and Modular Functions

Number Theory 2014-08-06 v1

Abstract

We give explicit upper bounds for the coefficients of arbitrary weight kk, level 2 cusp forms, making Deligne's well-known O(nk12+ϵ)O(n^{\frac{k-1}{2}+\epsilon}) bound precise. We also derive asymptotic formulas and explicit upper bounds for the coefficients of certain level 2 modular functions.
