| dc.description.abstractEn | We study actions of locally compact groups on von Neumann factors and the associated crossed-product von Neumann algebras. In the setting of totally disconnected groups we provide sufficient conditions on an action G Q ensuring that the inclusion Q ⊂ Q ⋊ G is irreducible and that every intermediate subfactor is of the form Q ⋊ H for a closed subgroup H < G. This partially generalizes a result of Izumi-Longo-Popa [ILP98] and Choda [Ch78]. We moreover show that one can not hope to use their strategy for non-discrete groups. | |
