%0 Journal Article %T Hypergeometric evaluation identities and supercongruences %A Ling Long %J Mathematics %D 2009 %I arXiv %X In this article, we provide an application of hypergeometric evaluation identities, including a strange valuation of Gosper, to prove several supercongruences related to special valuations of truncated hypergeometric series. In particular, we prove a conjecture of van Hamme. %U http://arxiv.org/abs/0912.0197v2
