Optimal transportation and the Einstein equation
The Ricci curvature is the basic ingredient in the Einstein equations of general relativity. In recent years the interpretation of Ricci curvature in Riemannian geometry has changed fundamentally via its characterization in terms of convexity properties of e.g. the Shannon-Bolzmann entropy of optimal transportation. In my talk I will explain the recent development of an analogous characterization of Ricci curvature and the Einstein equation in Lorentzian geometry.
