Daniel Drimbe, Stefaan Vaes
A variant of Gromov's notion of measure equivalence for groups has been introduced for II factors under different names. We propose the terminology of W*-correlated II fact…

Strong primeness for equivalence relations arising from Zariski dense subgroups
Daniel Drimbe, Cyril Houdayer
We show that orbit equivalence relations arising from essentially free ergodic probability measure preserving actions of Zariski dense discrete subgroups of simple algebraic groups…
