-finite von Neumann algebras and weakly almost periodic functions

Paul Jolissaint

Let be a von Neumann algebra which acts in a standard way on the Hilbert space , let be a subgroup of the group of all -automorphisms of . We prove that is …

Non Kazhdan's groups and a new approximation property for tracial von Neumann algebras

Paul Jolissaint

We define a new approximation property for tracial von Neumann algebras, called \textit{weakly mixing approximation property} which, for discrete groups and II factors, is equi…

The linear $\SL_2(\Z)$-action on $\T^n$: ergodic and von Neumann algebraic aspects

Paul Jolissaint, Alain Valette

The unique irreducible representation of $\SL_2(\R)$ on induces an action, called the \textit{linear action}, of $\SL_2(\Z)$ on the torus $\T^n$ for every . For …

Almost and weakly almost periodic functions on the unitary groups of von Neumann algebras

Paul Jolissaint

Let be a von Neumann algebra acting on the Hilbert space . We prove that is finite if and only if, for every and for all vectors $…

Examples of mixing subalgebras of von Neumann algebras and their normalizers

Paul Jolissaint

We discuss different mixing properties for triples of finite von Neumann algebras , and we introduce families of triples of groups whose associated von…

On the Relative Weak Asymptotic Homomorphism Property for Triples of Groups von Neumann Algebras

Paul Jolissaint

We provide a direct and elementary proof of the equivalence between the weak asymptotic homomorphism property for the pair of group von Neumann algebras and the…
