## What is... a gemoetric flow?

Mario Schulz talk

**Date:** 02.10.18 **Time:** 17.15 - 18.30 **Room:**

Geometric flows were originally an approach to solve geometric and topological problems. We introduce four different examples of geometric flows (the harmonic map heat flow, the mean curvature flow, the Ricci flow and the Yamabe flow) together with the corresponding geometric problem. Some animations will reveal differences and similarities between these flows. In the case of the Yamabe flow, we study the evolution of curvature which is given by a parabolic partial differential equation and derive basic estimates.
