Title: Facial structure of convex sets

Abstract: The facial structure of general closed convex cones can be rather complex (often surprisingly so). I will talk about different notions that capture the regularity properties of facial arrangements, which are important for a range of theoretical results and algorithms. In particular, I will focus on facial exposedness and facial dual completeness and the relation between then. I will talk about the Pataki sandwich theorem, introduce some new conditions and show illustrative examples.
