Free actions of polynomial growth Lie groups and classifiable C*-algebras
Ulrik Enstad, Gabriel Favre, Sven Raum
We show that any free action of a connected Lie group of polynomial growth on a finite dimensional locally compact space has finite tube dimension. This is shown to imply that the…

Detecting ideals in reduced crossed product C*-algebras of topological dynamical systems
Are Austad, Sven Raum
We introduce the -ideal intersection property for crossed product C*-algebras. It is implied by C*-simplicity as well as C*-uniqueness. We show that topological dynamical s…
