Abstract:

E. Effros and F. Hahn have conjectured that if $(G,Z)$ is a second countable locally compact transformation group, with $G$ amenable, then every primitive ideal of the associated ${C^\ast }$-algebra arises as the kernel of an irreducible representation induced from a stability subgroup. Results of Effros and Hahn concerning this conjecture are extended to include the twisted group algebra ${L^1}(G,A;T,\alpha )$, where $A$ is a separable type I ${C^\ast }$-algebra.
