Congruences involving the reciprocals of central binomial coefficients

Number Theory 2009-12-20 v2

Abstract

We present several congruences modulo a power of prime pp concerning sums of the following type k=1p1mkkr(2kk)1\sum_{k=1}^{p-1}{m^k\over k^r}{2k\choose k}^{-1} which reveal some interesting connections with the analogous infinite series.
