Resumen de Primeness and Primitivity Conditions for Twisted Group $C^*$-Algebras
Tron A. Omland
For a multiplier (2-cocycle) $\sigma$ on a discrete group $G$ we give conditions for which the twisted group $C^*$-algebra associated with the pair $(G,\sigma)$ is prime or primitive. We also discuss how these conditions behave on direct products and free products of groups.
