✦ Synopsis
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_{0}\left(C^{*}(G ; \sigma)\right)) into (\mathbb{R}). 1995 Academic Press.
