The polynomials are applied in many areas of mathematics, for instance, continued fractions, operator theory, analytic functions, interpolation, approximation theory, numerical analysis, electrostatics, statistical quantum mechanics, special functions, number theory, combinatorics, stochastic processes. On the other hand, generating functions have a great importance in special functions theory. The present study deals with some new properties of the Meixner polynomials in several variables. Firstly, we obtained some results include various families of multilinear and multilateral generating functions for the Meixner polynomials in several variables. In the last section, we get a theorem that gives a bilateral generating functions for these polynomials and the Lauricella functions. Finally, we derive some corollaries of the last theorem.
