Free Araki-Woods factors and Connes' bicentralizer problem

Cyril Houdayer

We show that for any free Araki-Woods factor $M = Γ (H_{R}, U_{t}) "$ of type $II I_{1}$ , the bicentralizer of the free quasi-free state $φ_{U}$ is trivial. Using Haagerup's…

Bass-Serre rigidity results in von Neumann algebras

Ionut Chifan, Cyril Houdayer

We obtain new Bass-Serre type rigidity results for $I I_{1}$ equivalence relations and their von Neumann algebras, coming from free ergodic actions of free products of groups on…
