Geometry & Topology Seminar: "Weak groupoid representations"
Seth Wolbert, Saint Louis University
Abstract: In this talk, I will introduce weak Lie groupoid actions, actions for which associativity is allowed to fail in a controlled manner. I will also explain how weak representations (weak groupoid actions on 2-vector bundles) are equivalent to representations up to homotopy and hence to VB-groupoids.
