Nathan Broomhead (Plymouth) "Thick subcategories, arc-collections and mutation"

Abstract: I will explain some work, in which I describe the lattices of thick subcategories of discrete derived categories. This is done using certain collections of exceptional and sphere-like objects related to non-crossing configurations of arcs in a geometric model.
