On a Hypergeometric Transformation Formula with Four Unconnected Bases (II)

Abstract

Twenty-five years back, Andrews [6] obtained a double series expansion for a series containing two independent bases, and deduced a number of mock theta function identities from it. A year later, Agarwal and Verma [3, 4] developed a theory of generalized hypergeometric series with two unconnected bases, and derived some transformation formulas involving such series by using contour integrals and the calculus of residues.
