Rigidity of geometric surface group actions

An action of a finitely generated group G on a manifold M is called ”geometric” if it comes from an embedding of G as a lattice in a Lie group acting transitively on M. In this talk, I will explain recent joint work with Maxime Wolff that characterizes geometric actions of surface groups on the circle by (a strong form of) topological rigidity.
