Abstract:  We prove that the constant terms of powers of a Laurent polynomial satisy certain congruences modulo prime powers. As a corollary, the generating series of these numbers considered as a function of a p-adic variable satifisies a non-trivial analytic continuation propety, similar to what B. Dwork showed for a class of hypergeometric series. The talk is based on a joint work with Anton Mellit.
