Orbit equivalence superrigidity for type III actions
Stefaan Vaes, Bram Verjans
We prove the first orbit equivalence superrigidity results for actions of type III when . These actions arise as skew products of actions of dense subgroups of $SL(n,\…

Classification results for nonsingular Bernoulli crossed products
Stefaan Vaes, Bram Verjans
We prove rigidity and classification results for type III factors given by nonsingular Bernoulli actions of the free groups and more general free product groups. This includes a la…

Spectral gap and strict outerness for actions of locally compact groups on full factors
Amine Marrakchi, Stefaan Vaes
We prove that an outer action of a locally compact group on a full factor is automatically strictly outer, meaning that the relative commutant of in the crossed product…
