Educational aims

The goal of the course is to provide an introduction to modern Geometric Measure Theory. Starting from the codimension 1 theory, namely the theory of sets of finite perimeter and BV functions, we move to the study of (generalized) oriented surfaces of arbitrary dimension and codimension. We illustrate basic structure and compactness results, leading to solutions to Plateau's problem, and in the final part of the course we deal with non-oriented surfaces (varifolds) and partial regularity results.
