An explicit Waldspurger formula for Hilbert modular forms II

Number Theory 2020-07-31 v2

Abstract

We describe a construction of preimages for the Shimura map on Hilbert modular forms using generalized theta series, and give an explicit Waldspurger type formula relating their Fourier coefficients to central values of twisted LL-functions. This formula extends our previous work, allowing to compute these central values when the main central value vanishes.
