Titre Dynamical alternating groups, stability, property Gamma, and inner amenability

Horaire14:00 à 15:00
RésumeWe study dynamical alternating groups associated to (topologically free, minimal) actions of countable amenable groups on the Cantor set. We show that these groups are stable in the sense of Jones and Schmidt, and their group von Neumann algebra has property Gamma (and in particular they are inner amenable). This is joint work with David Kerr.
