Ergodic cocycles in hyperbolic and Hadamard spaces
Corentin Le Bars
We consider discrete random dynamical systems induced by a non-elementary group action on a non-proper hyperbolic space. We prove that if the system is ergodic and satisfies the ``…

A Tits alternative for -buildings of type
Corentin Le Bars, Jean Lécureux, Jeroen Schillewaert
Let be a group with a non-elementary action on a (not necessarily discrete) -buildings. We prove that, given a random walk on , isometries in are strongly r…

Marches aléatoires et éléments contractants sur des espaces CAT(0)
Corentin Le Bars
This thesis is dedicated to random walks on spaces with non-positive curvature. In particular, we study the case of group actions on CAT(0) spaces that admit contracting elements,…
