On Products of Fourier Coefficients of Cusp Forms

Eric Hofmann, Winfried Kohnen

Published 2015-09-08Version 1

The purpose of this paper is to study products of Fourier coefficients of an elliptic cusp form, $a(n)a(n + r)$ $(n \geq 1)$ for a fixed positive integer $r$, concerning both non-vanishing and non-negativity.
