Maximal amenable von Neumann subalgebras arising from maximal amenable subgroups
Rémi Boutonnet, Alessandro Carderi
We provide a general criterion to deduce maximal amenability of von Neumann subalgebras arising from amenable subgroups of discrete countable groups . The cri…

Maximal amenable subalgebras of von Neumann algebras associated with hyperbolic groups
Rémi Boutonnet, Alessandro Carderi
We prove that for any infinite, maximal amenable subgroup in a hyperbolic group , the von Neumann subalgebra is maximal amenable inside . It provides many new, expl…
