Rigidity for boundary actions and classification in low dimensions
Apparaît dans la collection : 2024 - T2 - WS3 - Actions of large groups, geometric structures, and the Zimmer program
The plan of the talk is to describe joint work with A. Brown and Z. Wang on the smooth classification of actions of lattices in SL(n,R) on n-1 dimensional manifolds. The method is also amenable to show rigidity for some boundary actions.
