Central twisted transformation groups and group C*-algebras of central group expansions
Central twisted transformation groups and group C*-algebras of central group expansions
We examine the structure of central twisted transformation group C * -algebras C 0 (X) id,u G, and apply our results to the group C * -algebras of central group extensions.Our methods require that we study Moore's cohomology group H 2 (G, C(X, T)), and, in particular, we prove an …
