DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GPRTatNU/16/
 ">Moduli of principal bundles for 2-groups</a>\nby Emily Cliff (University
  of Sydney) as part of Geometry\, Physics\, and Representation Theory Semi
 nar\n\n\nAbstract\nA 2-group is a categorified version of a group. In this
  talk\, we will study the structure of moduli stacks and spaces of princip
 al bundles for 2-groups. In a special case where the isomorphism classes o
 f objects in our 2-group form a finite (ordinary) group $G$\, we show that
  the moduli stack provides a higher-categorical enhancement of the Freed--
 Quinn line bundle appearing in Chern--Simons theory for the finite group $
 G$. This is joint work with Eric Berry\, Dan Berwick-Evans\, Laura Murray\
 , Apurva Nakade\, and Emma Phillips.\n
