Abstract

We define two common qq-orthogonal polynomials: homogeneous qq-Laguerre polynomials and homogeneous little qq-Jacobi polynomials. They can be viewed separately as solutions to two qq-partial differential equations. Then, we proved that if an analytic function satisfies a certain system of qq-partial differential equations, if and only if it can be expanded in terms of homogeneous qq-Laguerre polynomials or homogeneous little qq-Jacobi polynomials. As applications, we obtain generalizations of the Ramanujan qq-beta integrals and Andrews-Askey integrals. Additionally, we present an operator representation of qq-Laguerre polynomials that facilitates the computation of identities involving qq-Laguerre polynomials.
