*Mittwoch, 30. Juni 2010, ab 16:15 Uhr, Seminarraum Olga Taussky-Todd (C 
209), UZA 4*

*Mathematisches Kolloquium – Einladung zu einem Vortrag im Rahmen der 
Habilitation von *

*Dr. Jakob Kellner (Forschungsplattform „Kurt Gödel Research Center“: 
**„Forcing“*

* *

*Abstract: I will give a ridiculously brief introduction to mathematical logic and set theory, a very sketchy overview of the method of forcing, and I will mention some recent developments in forcing. The talk (or at least the first half) should be accessible to a general mathematical audience*.

*Donnerstag, 1. Juli 2010, ab 14:00 Uhr, HS 2, UZA 2*

*Außerordentliches Mathematisches Kolloquium*

*Prof. Dr. Simon Brendle (Stanford  University): „Curvature, Sphere, Theorems, and the Ricci Flow“*

*  *

*Abstract:*

*In 1926, Hopf proved that any compact, simply connected Riemannian manifold with constant curvature 1 is isometric to the standard sphere. Motivated by this result, Hopf posed the question of whether a compact, simply connected manifold with suitably pinched curvature is topologically a sphere. This question has been studied by many authors over the past six decades, a milestone being the Topological Sphere Theorem proved by Berger and Klingenberg in 1960.*

*  *

*In this lecture, I will discuss the history of this problem, and describe the proof (joint with R. Schoen) of the Differentiable Sphere Theorem. This theorem classifies all manifolds with 1/4-pinched curvature up to diffeomorphism. The distinction between homeomorphism and diffeomorphism is significant in light of the exotic spheres constructed by Milnor; the proof uses the Ricci flow technique introduced byHamilton.*
