Abstract
In 1984, Greene introduced the notion of hypergeometric functions over finite fields. Special values of these functions have recently been of interest as they are related to numbers of F_p points on algebraic varieties and to Fourier coefficients of modular forms. In this talk, we discuss a general modulo p^3 congruence for these functions which yields extensions to recent supercongruences of Ono-Ahlgren, Loh-Rhodes, and of Mortenson. This is joint work with Carsten Schneider (Linz).
