报告摘要：The mission of this talk is to find two general q-operational equations together with the expansion issue of the bivariate q-Laguerre polynomials from the perspective of q-partial differential equations. We also give some applications including some q-Hardy--Hille type formulas and the generalized Askey--Wilson polynomials. In addition, we present the Rogers-type formulas and the U(n+1)-type generating functions for the bivariate q-Laguerre polynomials by the technique based upon q-operational equations. Moreover, we derive a new generalized Andrews--Askey integral and a new transformation identity involving the bivariate q-Laguerre polynomials by applying q-operational equations. Finally, we find q-operational equations and q-partial differential equations for the generalized Askey--Wilson polynomials and give some applications.
