group of linear automorphisms of A . In this paper, we compute the multiplicative n β · Ε½ G . structure on the Hochschild cohomology HH A of the algebra of invariants of n β · Ε½ 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
1999, J. Algebra, 221, 293α314 . This allows us to construct various non-parabolic subalgebras of H H . We construct all the irreducible representations of H H as n, r n, r induced modules from such subalgebras. We show the existence of a partition of unity in H H , which is specialized to a partiti
