On the occurrence of Hecke eigenvalues in sectors

Abstract

Let π\pi be a non-self-dual unitary cuspidal automorphic representation of non-solvable polyhedral type for GL(2) over a number field. We show that π\pi has a positive upper Dirichlet density of Hecke eigenvalues in any sector whose angle is at least 2.63 radians.
