Mixed moment of and -functions in the level aspect
arXiv:2609.16893 · doi:10.1090/proc/17898
Abstract
In this paper, we establish an asymptotic formula of mixed moments of and for cusp forms of weight , prime level and real primitive nebentypus modulo in the level aspect with a power-saving error term. As an application, we deduce the simultaneous non-vanishing of and for sufficiently large prime levels.
