Abstract

We create the homogeneous q-di erence operator e E(a; b;  ) as an extension of the exponential operator E(b ). A new polynomials hn(a; b; xjq????1) are de ned as an extension of the q????1-Rogers-Szego polynomial hn(a; bjq????1). We provide an operator proof of the generating function and its extension, Rogers formula and the invers linearization formula, and Mehler's formula for the polynomials hn(a; bjq????1). The generating function and its extension, Rogers formula and the invers linearization formula, and Mehler's formula for the polynomials hn(a; bjq????1) are deduced by giving special values to parameters of a new polynomial hn(a; b; xjq????1).
