The goal of this paper is to examine the relationship between a domain \(R\) and its subring of invariants \(R^{L}\), under the action of a finite-dimensional restricted Lie algebra \(L\). We first show that there exists a nondegenerate \(\left(R^{L}, R^{L}\right)\)-bimodule "trace-like" map \(g: R
group of linear automorphisms of A . In this paper, we compute the multiplicative n โ ท ลฝ G . structure on the Hochschild cohomology HH A of the algebra of invariants of n โ ท ลฝ G . G. We prove that, as a graded algebra, HH A is isomorphic to the graded n algebra associated to the center of the group al
