F. Schulze - An introduction to weak mean curvature flow 1
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 Brakke flows, their basic properties and how

Abstract: In the last few years, we have been active in the development of geometry-inspired measures for the edge-based characterization of real-world complex networks. In particular, we were first to introduce a discretization of the classical Ricci curvature proposed by R. Forman to the

http://www.teachastronomy.com/ General relativity relates the dynamics of the expanding universe to the curvature of space. Thus space curvature is one of the most important things to measure about our universe, but it's an extremely difficult measurement because the curvature is so subtl

A. Mondino - Metric measure spaces satisfying Ricci curvature lower bounds 1 (version temporaire)
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-Hausdorff limits of smooth Riemannian manifolds
