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
By the method of cyclic cohomology we prove that all tracial states on a twisted group \(C^{*}\)-algebra \(C^{*}(G ; \sigma)\), where \(G\) is a torsion free discrete group of polynomial growth and \(\sigma\) is a 2-cocycle on \(G\) with values in the unit circle group, induce the same map from \(K_
