Spring 2019 Analysis Student Seminar
This semester, we will learn about regularity of minimal surfaces
in higher codimension. We will start with an introduction of Geometric
Measure Theory, more specifically the FedererFleming theory of
integral currents. Then, we will cover the classical theory of
regularity in codimension 1. After understanding what are the
obstructions to generalize this theory to higher condimensions, we
will move onto regularity of minimal surfaces in codimension bigger
than 1. There are no prerequisites besides basic knowledge of functional analysis, measure theory, and differential geometry.
