Symmetric polynomials in the free metabelian Poisson algebras
Abstract
Let K be a field of characteristic zero and Xn={x1,…,xn} be a finite set of variables. Consider the free metabelian Poisson algebra Pn of rank n generated by Xn over K. An element in Pn is called symmetric if it is preserved under any change of variables, i.e. under the action of each permutation in Sn. In this study, we determine the algebra PSnn of symmetric polynomials of Pn.
