Abstract

The authors establish a set of two presumably new theta-function identities which are based upon q-binomial theorem and Heine’s transformations. Several closely-related identities such as (for example) q-product identities and Jacobi’s triple-product identity are also considered.

Keywords: Jacobi’s triple-product identity, q-Product identities, Euler’s Pentagonal Number Theorem, q-Binomial theorem, Heine’s transformations
