Abstract
We study Andrews and Berndt’s organization of Ramanujan’s transformation formulas in Chapter 1 of their book Ramanujan’s Lost Notebook, Part II. In the process, we rediscover a bibasic Heine’s transformation, which follows from a Fundamental Lemma given by Andrews in 1966, and obtain identities proximal to Ramanujan’s entries. We also provide a multibasic generalization of Andrews’ 1972 theorem concerning a q-analog of the Lauricella function. Our results only require the q-binomial theorem, and are an application of what Andrews and Berndt call ‘Heine’s Method’.
