W*-superrigidity for group von Neumann algebras of left-right wreath products
Mihaita Berbec, Stefaan Vaes
We prove that for many nonamenable groups Γ, including all hyperbolic groups and all nontrivial free products, the left-right wreath product group G := (Z/2Z)^(Γ) \rtimes (Γ\times…

Type III factors with unique Cartan decomposition
Cyril Houdayer, Stefaan Vaes
We prove that for any free ergodic nonsingular nonamenable action Γ \actson (X,μ) of all Γ in a large class of groups including all hyperbolic groups, the associated group measure…

Unique Cartan decomposition for II_1 factors arising from arbitrary actions of hyperbolic groups
Sorin Popa, Stefaan Vaes
We prove that for any free ergodic probability measure preserving action $Γ\actson (X,μ)$ of a non-elementary hyperbolic group, or a lattice in a rank one simple Lie group, the ass…
