Structural properties of dendrite groups
Bruno Duchesne, Nicolas Monod
Let G be the homeomorphism group of a dendrite. We study the normal subgroups of G. For instance, there are uncountably many non-isomorphic such groups G that are simple groups. Mo…

Group actions on dendrites and curves
Bruno Duchesne, Nicolas Monod
We establish obstructions for groups to act by homeomorphisms on dendrites. For instance, lattices in higher rank simple Lie groups will always fix a point or a pair. The same hold…

Groups acting on spaces of non-positive curvature
Bruno Duchesne
In this survey article, we present some panorama of groups acting on metric spaces of non-positive curvature. We introduce the main examples and their rigidity properties , we show…
