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_
It is well known that the complexification of the complement of the arrangement of reflecting hyperplanes for a finite Coxeter group is an Eilenberg-MacLane space. In general, the cohomology of the complement of a general complex arrangement is well behaved and well understood. In this paper we cons
