J. Wang - Topological rigidity and positive scalar curvature

Autor: Wang, Jian, Béchet, Hugo, Bastien, Fanny

In this talk, we shall describe some topological rigidity and its relationship with positive scalar curvature. Precisely, we will present a proof that a complete contractible 3-manifold with positive scalar curvature is homeomorphic to the Euclidean

C. Sormani - Intrinsic Flat and Gromov-Hausdorff Convergence 3

Autor: Sormani, Christina, Bastien, Fanny, Béchet, Hugo

We introduce various notions of convergence of Riemannian manifolds and metric spaces. We then survey results and open questions concerning the limits of sequences of Riemannian manifolds with uniform lower bounds on their scalar curvature. We close

A. Mondino - Metric measure spaces satisfying Ricci curvature lower bounds 2

Autor: Mondino, Andrea, Bastien, Fanny, Béchet, Hugo

The idea of compactifying the space of Riemannian manifolds satisfying Ricci curvature lower bounds goes back to Gromov in the '80ies and was pushed by Cheeger-Colding in the ‘90ies, who investigated the structure of spaces arising as Gromov-Hausdo

Limites de courbures de Ricci temporelles via transport optimal

Autor: Mondino, Andrea, Bastien, Fanny, Béchet, Hugo

The goal of the talk is to present a recent work in collaboration with Cavalletti (SISSA) on optimal transport in Lorentzian synthetic spaces. The aim is to set up a “Lorentzian analog” of the celebrated Lott-Sturm-Villani theory of CD(K,N) metri

T. Richard - Advanced basics of Riemannian geometry 3

Autor: Richard, Thomas, Bastien, Fanny, Béchet, Hugo

We will present some of the tools used by the more advanced lectures. The topics discussed will include : Gromov Hausdorff distance, comparison theorems for sectional and Ricci curvature, the Bochner formula and basics of Ricci flow.

F. Schulze - An introduction to weak mean curvature flow 1

Autor: Schulze, Felix, Bastien, Fanny, Béchet, Hugo

It has become clear in recent years that to understand mean curvature flow through singularities it is essential to work with weak solutions to mean curvature flow. We will give a brief introduction to smooth mean curvature flow and then discuss Brak
