In mathematics, an elliptic hypergeometric series is a series Σ''c''''n'' such that the ratio ''c''''n''/''c''''n''−1 is an elliptic function of ''n'', analogous to generalized hypergeometric series where the ratio is a rational function of ''n'', and basic hypergeometric series where the ratio is a periodic function of the complex number ''n''. They were introduced by in their study of elliptic 6-j symbols.
