A higher rank shifted convolution problem with applications to L‐functions
Abstract
Abstract While several instances of shifted convolution problems for have been solved, the case where one factor is the classical divisor function and one factor is a Fourier coefficient has remained open. We solve this case in the present paper. The proof involves two intertwined applications of different types of delta symbol methods. As an application we establish an asymptotic formula for central values of ‐functions for a automorphic form twisted by Dirichlet characters to moduli .
