A bibasic double sum extension of a -binomial theorem arising out of subspace enumeration
Gaurav Bhatnagar, Amritanshu Prasad
We prove a conjecture that arose in the context of a subspace enumeration problem over finite fields. We prove, more generally, a bibasic, double-sum identity, which extends a -…

Expansion formulas for elliptic hypergeometric series
Gaurav Bhatnagar, Archna Kumari
We provide an alternate approach to obtaining expansion formulas on the lines of the well-poised Bailey lemma. We recover results due to Spiridonov and Warnaar and one new formula…
