%0 Journal Article %T $_3F_2$ hypergeometric series and periods of elliptic curves %A Dermot McCarthy %J Mathematics %D 2009 %I arXiv %X We express the real period of a family of elliptic curves in terms of classical hypergeometric series. This expression is analogous to a result of Ono which relates the trace of Frobenius of the same family of elliptic curves to a Gaussian hypergeometric series. This analogy provides further evidence of the interplay between classical and Gaussian hypergeometric series. %U http://arxiv.org/abs/0906.4508v1
