Representations up to homotopy are weak groupoid actions
Speaker: Seth Wolbert, University of Illinois at Urbana-Champaign
Abstract: In this talk, I will introduce weak groupoid representations. These are weak 2-functors from a groupoid $G$ into a version of the frame bundle generalized for VB-groupoids. I will also describe how (2-term) representations up to homotopy are in fact weak groupoid representations. With this identification in mind, one may reformulate the equivalence between 2-term representations and VB-groupoids as an equivalence between weak groupoid representations and their associated action groupoids.
