DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TQFT/87/">In
 vertible TQFTs and Atiyah–Singer index theory</a>\nby Markus Upmeier (Un
 iversity of Aberdeen) as part of Topological Quantum Field Theory Club (IS
 T\, Lisbon)\n\n\nAbstract\nI will discuss work in progress that constructs
  a categorification of Atiyah-Singer index theory. My main theorem shows t
 hat these new\, categorical indices can be organized into an invertible TQ
 FT\, which can algebraically be viewed as a categorical group representati
 on of a cobordism category. If time permits\, I will outline how to comput
 e the categorical index topologically.\n
