MPI-Oberseminar

Posted in
Organiser(s): 
C. Kaiser
Date: 
Thu, 2013-01-31 15:00 - Thu, 2026-12-31 16:00
Location: 
MPIM Lecture Hall

The Oberseminar is a very long running seminar at MPI (‘Ober‘ standing for 'upper'). Its idea is that the guests of the MPI speak in this seminar (hopefully early in their stay) and get the chance to explain their work to the other guests.

Friedrich Hirzebruch Lecture

Location: 
University Club Bonn

The annual Friedrich Hirzebruch Lecture is a series of lectures started in 2007 on the occasion of the 80th birthday of Prof. Friedrich Hirzebruch. The lectures address a general audience and aim at illustrating the relation between mathematics and art, society and other fields.

Workshop on Young Researchers in String Mathematics

November 27 - 30, 2017

 

The workshop is an occasion to foster interactions and initiate new collaborations between young researchers active in Germany and nearby countries, who are all interested in mathematical aspects of string theory: mirror symmetry, enumerative geometry of curves (Gromov-Witten theory, Donaldson-Thomas, stable pair invariants, ...) and their modularity, integrability, and algebraic properties, tropical geometry, topological recursion, wall-crossing phenomena and Bridgeland stability conditions, relations to gauge theory, geometric quantization, conformal field theory, etc.

"Descartes, Euler, Gauss: From surfaces to integers". Hirzebruch lecture by Werner Ballmann on Monday, November 13

Geometric quantities of a surface, like distance, angle, or area, change when the surface is deformed. Euler discovered a quantity, the Euler characteristic, which remains unchanged. The formula of Gauss-Bonnet, a landmark result of mathematics, relates Euler characteristic with geometry. In the talk, I will present ideas of Descartes, Euler, and Gauss related to this formula.

In this talk, I will present new tools and methods in the study of  the trend to equilibrium of gradient flows in metric spaces  $(\mathcal{M},d)$ in the entropy and metric sense, to establish decay rates, finite time of extinction, and to characterise Lyapunov stable equilibrium points. More precisely,

In the celebrated paper [2], Li and Yau proved the parabolic Harnack inequality for Riemannian manifolds with Ricci curvature bounded from below. The key step in their proof was a completely new type of Harnack estimate, namely a pointwise gradient estimate, called {\em differential Harnack inequality}, which, by integration along a path, yields the classical parabolic Harnack estimate. If one tries to apply this method to discrete structures (graphs) one is faced with two big obstacles.
