Julian Scheuer: The curvature flow approach to geometric inequalities

4:00pm, CM219

The isoperimetric problem (fencing the largest possible area with a fence of given length) is one of the oldest problems in mathematics and can be traced back to greek mythology. In many classical settings it is well understood, whereas in complicated geometries it still gives rise to yet unsolved questions.
On the other hand, in the recent decades a fruitful analytical tool has emerged, namely the smooth deformation of complicated geometric objects to simpler ones by a so-called curvature flow. This method has culminated in the proof of the Poincaré conjecture by Hamilton and Perelman.
In this colloquium we have a look at the power of curvature flows to attack the isoperimetric and related problems. The methods are on the edge between partial differential equations and differential geometry, not hesitating to mention that no technicalities will play a role in this presentation.
