Rigidity of topological entropy on manifolds carrying a metric of constant negative curvature

Let X be a compact connected locally symmetric Riemannian manifold of negative curvature. For any Riemannian manifold Y topologically related to X, Besson, Courtois, and Gallot proved a relation between the volume entropies of Y and X. In particular, their result implies Mostow's rigidity theorem. We will discuss the steps in the proof of their result in the case when X has constant negative curvature, Y is negatively curved, and X and Y are homotopy equivalent. The main reference is "Minimal entropy and Mostow's rigidity theorems" by Besson, Courtois, and Gallot.

Static 3-manifolds with positive scalar curvature

In this talk, we will survey some results on static manifolds in dimension 3 with positive scalar curvature. These objects arise naturally in General Relativity and play an important role when studying the analytical properties of the operator which takes a Riemannian metric to its scalar curvature function. There is a conjectural classification and we will discuss classical work by Kobayashi and recent work by Ambrozio in this direction.
