Examples of property (T) II $_{1}$ factors with trivial fundamental group

Ionut Chifan, Sayan Das, Cyril Houdayer +1

In this article we provide the first examples of property (T) $I I_{1}$ factors $N$ with trivial fundamental group, $F (N) = 1$ . Our examples arise as gro…

Connes' bicentralizer problem for q-deformed Araki-Woods algebras

Cyril Houdayer, Yusuke Isono

Let $(H_{R}, U_{t})$ be any strongly continuous orthogonal representation of $R$ on a real (separable) Hilbert space $H_{R}$ . For any $q \in (- 1, 1)$ , we den…
