Unique Cartan decomposition for II_1 factors arising from arbitrary actions of free groups
Sorin Popa, Stefaan Vaes
We prove that for any free ergodic probability measure preserving action \F_n \actson (X,μ) of a free group on n generators \F_n, 2 \leq n \leq \infty, the associated group measure…

Stable orbit equivalence of Bernoulli actions of free groups and isomorphism of some of their factor actions
Niels Meesschaert, Sven Raum, Stefaan Vaes
We give an elementary proof for Lewis Bowen's theorem saying that two Bernoulli actions of two free groups, each having arbitrary base probability spaces, are stably orbit equivale…

A class of II_1 factors with many non conjugate Cartan subalgebras
An Speelman, Stefaan Vaes
We construct a class of II_1 factors M that admit unclassifiably many Cartan subalgebras in the sense that the equivalence relation of being conjugate by an automorphism of M is co…
