An expansion formula for elliptic hypergeometric series
An expansion formula for elliptic hypergeometric series
We prove an expansion formula for elliptic hypergeometric series. In the $q$-case, when the nome $p=0$, it generalizes $q$-hypergeometric transformation formulas due to Liu, and Wang and Ma, results that are used to derive identities for Hecke-type series and transformations for false and mock-theta functions. Our formula contains an arbitrary …
