Irreducibly represented groups

Bachir Bekka, Pierre de la Harpe

A group is irreducibly represented if it has a faithful irreducible unitary representation. For countable groups, a criterion for irreducible representability is given, which gener…

Operator-algebraic superrigidity for $S L_{n} (Z), n \geq 3$

Bachir Bekka

For $n \geq 3,$ let $Γ = S L_{n} (Z) .$ We prove the following superridigity result for $Γ$ in the context of operator algebras. Let $L (Γ)$ be the von Neumann algebra generated by…
