Topics in analysis on metric spaces
Topics in analysis on metric spaces
EPFL March/April 2010
Marc Troyanov (EPFL) and Felix Stephane (University of Bonn)
The main goal of these lectures is to give a gentle introduction to the theory of optimal mass transport theory and its applications in Riemannian and metric geometry. We will try to be as elementary as possible.
We will discuss in particular the following topics:
- Introduction to Optimal Transport Theory (Monge-Kantorovitch problem)
- The Wasserstein distance between measures.
- The Riemannian case and relations to Ricci curvature.
- Generalization to metric measure spaces.
