Abstract

In many cases one may encounter an integral which is of $q$-Mellin--Barnes type. These integrals are easily evaluated using theorems which have a long history dating back to Slater, Askey, Gasper, Rahman and others. We derive some interesting $q$-Mellin--Barnes integrals and using them we derive transformation and summation formulas for nonterminating basic hypergeometric functions. The cases which we treat include ratios of theta functions, the Askey--Wilson moments, nonterminating well-poised $}_3\phi_2$, nonterminating very-well-poised $}_5W_4$, $}_8W_7$, products of two nonterminating $}_2\phi_1$'s and squares of a nonterminating well-poised $}_2\phi_1$.
