We define a function which extends Gaussian hypergeometric series to the
p-adic setting. This new function allows results involving Gaussian
hypergeometric series to be extended to a wider class of primes. We demonstrate
this by providing various congruences between the function and truncated
classical hypergeometric series. These congruences provide a framework for
proving the supercongruence conjectures of Rodriguez-Villegas.Comment: Int. J. Number Theory, accepted for publicatio
