Explicit formulas and vanishing conditions for certain coefficients of Drinfeld-Goss Hecke eigenforms
arXiv:1705.09795
Abstract
We obtain a closed form polynomial expression for certain coefficients of Drinfeld-Goss double-cuspidal modular forms which are eigenforms for the degree one Hecke operators with power eigenvalues, and we use those formulas to prove vanishing results for an infinite family of those coefficients.
