About the Course

In this course, I want to give an overview on the analysis of the mean curvature flow equation, in particular from the point of view of PDEs and calculus of variations. Mean curvature flow arises in many applications inside and outside of mathematics and has been widely studied over the last decades.?We will start understanding the PDE?by studying?strong solutions, the evolution of various geometric quantities,?and constructing special solutions.?Then, we will discuss several weak solution concepts, namely?viscosity solutions based on the comparison principle,?distributional solutions based on the gradient flow structure, and varifold solutions based on local energy dissipation. We will show that?mean curvature flow arises as the singular limit of simple PDEs,?as?the limit of (sequences of) variational problems, and as the limit of the computationally efficient thresholding scheme. If time permits, we will discuss multiphase mean curvature flow.

Prerequisites

Working knowledge in Functional Analysis,?PDEs, and basic knowledge of Differential Geometry?are assumed. Basic concepts from Geometric Measure Theory are useful but not necessary to follow the course.
