A rigidity result for crossed products of actions of Baumslag-Solitar groups
Niels Meesschaert
Let BS(n_1,m_1) X_1 and BS(n_2,m_2) X_2 be two ergodic essentially free probability measure preserving actions of nonamenable Baumslag-Solitar…

Partial classification of the Baumslag-Solitar group von Neumann algebras
Niels Meesschaert, Stefaan Vaes
We prove that the rational number |n/m| is an invariant of the group von Neumann algebra of the Baumslag-Solitar group BS(n,m). More precisely, if L(BS(n,m)) is isomorphic with L(\…

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…
