Coarse embeddings and group actions preserving rigid geometric structures

By Charles Frances

Also appears in collection : 2024 - T2 - WS3 - Actions of large groups, geometric structures, and the Zimmer program

We will see how the notion of coarse embeddings allows to better understand discrete group actions preserving a rigid geometric structure. The focus will mainly be on isometric and conformal actions. In particular, we will discuss a Tits alternative for isometry groups of compact Lorentzian manifolds.
