About the course: We will explore a variety of topics
in convex and geometry and analysis, moving from classical
theorems and techniques to recent results and open problems.
Possible topics include: Brunn-Minkowski and
isoperimetric inequalities; symmetrization methods; concentration
phenomena; geometric versions of Hahn-Banach;
Legendre transform; extreme points and the
Krein-Milman theorem; monotone and convex matrix functions.
