Title

Faces of convex sets: dimensions and regularity

Abstract

The facial structure of convex sets can be surprisingly complex, and unexpected irregularities of the arrangements of faces give rise to badly behaved sets. I will focus on specific properties of facial structure that capture irregularities (dimensions of faces, singularity degree, facial exposure and facial dual completeness). I will also talk about some classic results related to faces of convex sets, mention new results and counterexamples and will relate this to some open problems.
