Generating Functions of (p, q)-Analogue of I-Function Satisfying Truesdell’s Ascending and Descending $$F_{p,q}$$-Equation

This paper contains different forms of I-function which satisfies Truesdell’s ascending and descending \(F_{p,q}\)-equation. Then certain generating functions have been obtained by using these various structures. Some cases of these outcomes as for as (p, q)-analogue of G- and H-functions have likewise been obtained.
