Some Generating Functions of Two Variables Laguerre Polynomials L^α_n (x,y) from the View Point of Lie-Algebra

Laguerre polynomials have special importance in engineering, science and good model for many systems in various fields. In this paper we consider a six parameters lie-group for these polynomials, which doesnt seem to appear before. By means of Weisners group theoretic method some new generating functions of two variable and one parameter Laguerre polynomials L^α_n (x,y) are obtained from which several generating functions can be easy derived.
