4-manifolds and their mapping class groups from a Thurstonian point of view
Description
In this talk, I will describe a point of view on 4-manifold theory inspired by Thurston's approach to 2-manifolds and 3-manifolds. I will try to explain how this approach connects to topics such as Teichmuller Theory, number theory and the theory of reflection groups. Most of this story still unwritten.
