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
Many rings that have enjoyed growing interest in recent years, e.g., quantum enveloping algebras, quantum matrices, certain Witten-algebras, . . . , can be presented as generalized Weyl algebras. In the paper we develop techniques for calculating dimensions, here mainly the Krull dimension in the se
