Abstract: | We show that every twisted action ( , ) of a locally compactgroup G on a C*-algebra A is Morita equivalent to an ordinaryaction of G/N , where N is the domain of . This result allowsus to apply many results known for ordinary covariant systemsto the more general twisted case. Especially, this is true forresults which are obtained by the Mackey machine. |
