Mittagsseminar: Pierre Colmez (Paris): p-adic curves
We will explain how to decompose a p-adic curve in a way reminiscent to the pants decompositions of Riemann surfaces, and how to use this to compute the cohomol...

Kolloquium Wilhelm Killing: Prof. Dr. Gérard Besson (Grenoble): Compactness results for non positively curved metric measured spaces
This is a joint work with G. Courtois, S. Gallot and A. Sambusetti. We will study some compact metric spaces satisfying weak versions of curvature assumptions. ...
