By means of a symbolic method, in this paper we introduce a new
family of multivariate polynomials such that multivariate Levy pro-
cesses can be dealt with as they were martingales. In the univariate
case, this family of polynomials is known as time-space harmonic poly-
nomials. Then, simple closed-form expressions of some multivariate
classical families of polynomials are given. The main advantage of this
symbolic representation is the plainness of the setting which reduces
to few fundamental statements but also of its implementation in any
symbolic software. The role played by cumulants is emphasized within
the generalized Hermite polynomials. The new class of multivariate
Levy-Sheer systems is introduced
