Geometric Measure Theory
Prerequisiti
Basic knowledge of Measure Theory and Functional Analysis.
Programma
Part I: Variational problems with surface energies. Sets of finite perimeter, Sobolev spaces and BV functions. Compactness and lower semicontinuity in BV. SBV functions. Compactness and lower semicontinuity in SBV.
Part II: Plateau's and its weak formulation. Federer Fleming theory of currents, closure, compactness, boundary rectifiability.
Part III: Mean curvature motion. Level set formulation and Brakke's solutions. Existence of solutions via elliptic regularization.
Obiettivi formativi
The aim of the course is to present the basic concepts of Geometric Measure Theory. The course is organised according to specific goals, hence the tools and techniques will be introduced according to the goals.
