DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QGS/17/">On 
 fusion 2-categories</a>\nby David Reutter (Max Planck Institute for Mathem
 atics\, Germany) as part of Quantum Groups Seminar [QGS]\n\n\nAbstract\nI 
 will revisit and categorify concepts from the theory of fusion categories 
 — including idempotent completeness and semi-simplicity\, ultimately lea
 ding to a notion of `fusion 2-category’. I will highlight structural sim
 ilarities and differences between fusion 1- and 2-categories and discuss s
 everal concrete examples. If time permits\, I will discuss the role of fus
 ion 2-categories as a natural building block for 4-dimensional topological
  field theories.\n
