The dual structure of crossed product C*-algebras with finite groups
We study the space of irreducible representations of a crossed product C*-algebra A⋊σ G, where G is a finite group. We construct a space Γ which consists of pairs of irreducible representations of A and irreducible projective representations of subgroups of G. We show that there is a natural action of G on Γ and that the orbit space G\Γ corresponds bijectively to the dual of A⋊σG. © 2013 Australian Mathematical Publishing Association Inc.
