Abstract

Given a finite dimensional Lie algebra over a field of prime characteristic.We shall consider the factorial properties of the center and semi-center of its enveloping algebra and find analogs of theorems due to J.Dixmier and C.Moeglin in the zero char.case.In a different strand we will describe analogs of theorems due to R.P.Stanley and H.Nakajima,in the context of polynomial invariants of finite groups.This naturally leads to the study of Lie algebra polynomial invariants and relative(semi-)invariants,and we present results in this direction.
