Extension problems and non-abelian duality for $C^{*}$ -algebras

Astrid an Huef, S. Kaliszewski, Iain Raeburn

Suppose that $H$ is a closed subgroup of a locally compact group $G$ . We show that a unitary representation $U$ of $H$ is the restriction of a unitary representation of $G$ if and…

Twisted actions and the obstruction to extending unitary representations of subgroups

Astrid an Huef, Iain Raeburn

Suppose that $G$ is a locally compact group and $π$ is a (not necessarily irreducible) unitary representation of a closed normal subgroup $N$ of $G$ on a Hilbert space $H$ . We exte…
