Real zeros of holomorphic Hecke cusp forms
This note is concerned with the zeros of holomorphic Hecke cusp forms of large weight on the modular surface. The zeros of such forms are symmetric about three geodesic segments and we call those zeros that lie on these segments, real. Our main results give estimates for the number of real zeros as the weight goes to infinity. Mathematics Subject Classification (2010). Primary: 11F11, 11F30. Se...
متن کاملReal Zeros of Holomorphic Hecke Cusp Forms and Sieving Short Intervals
We study so-called real zeros of holomorphic Hecke cusp forms, that is zeros on three geodesic segments on which the cusp form (or a multiple of it) takes real values. Ghosh and Sarnak, who were the first to study this problem, showed that existence of many such zeros follows if many short intervals contain numbers whose all prime factors belong to a certain subset of the primes. We prove new r...
متن کاملHecke Structure of Spaces of Half-integral Weight Cusp Forms
We investigate the connection between integral weight and half-integral weight modular forms. Building on results of Ueda 14], we obtain structure theorems for spaces of half-integral weight cusp forms S k=2 (4N;) where k and N are odd nonnegative integers with k 3, and is an even quadratic Dirichlet character modulo 4N. We give complete results in the case where N is a power of a single prime,...
متن کاملFourier Coefficients of Hilbert Cusp Forms Associated with Mixed Hilbert Cusp Forms
We express the Fourier coefficients of the Hilbert cusp form Lhf associated with mixed Hilbert cusp forms f and h in terms of the Fourier coefficients of a certain periodic function determined by f and h. We also obtain an expression of each Fourier coefficient of Lhf as an infinite series involving the Fourier coefficients of f and h.
متن کاملExplicit Results on the Distribution of Zeros of Hecke L-functions
We prove an explicit log-free zero density estimate and an explicit version of the zero-repulsion phenomenon of Deuring and Heilbronn for Hecke L-functions. In forthcoming work of the second author, these estimates will be used to establish explicit bounds on the least norm of a prime ideal in a congruence class group and improve upon existing explicit bounds for the least norm of a prime ideal...
