2:00 PM - 3:00 PM
This talk is based on a recent joint work with Wen-Ching Winnie Li and Ling Long. We consider the hypergeometric data corresponding to a formula due to Whipple which relates certain hypergeometric values and . When the hypergeometric data are primitive and defined over , from identities of hypergeometric character sums, we explain a special structure of the corresponding Galois representations behind Whipple’s formula leading to a decomposition that can be described by the Fourier coefficients of Hecke eigenforms. In this talk, I will use an example to demonstrate our approach and relate the hypergeometric values to certain periods of modular forms.
