Titre Orderable groups arising from Cantor dynamical systems
Horaire14:00 à 15:00
RésumeTo every homeomorphism of the Cantor set, we associate a group of homeomorphisms of the real line. It is defined by an action on the mapping torus of the dynamical system which preserve each orbit of the suspension flow. I will explain how this produces a class of finitely generated simple groups of homeomorphisms of the real line, and investigate further properties of this construction.
This is a joint work with Michele Triestino.
