DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TQFT/145/">T
 he homotopy coherent classification of fusion 2-categories</a>\nby Julia P
 lavnik (Indiana University) as part of Topological Quantum Field Theory Cl
 ub (IST\, Lisbon)\n\n\nAbstract\nFusion 2-categories are a higher categori
 cal analog of fusion categories that have gained a lot of attention in the
  last years because of their importance in many fields of math and physics
 \, such as TQFTs\, condensed matter physics  and high energy physics. The 
 classifiction of fusion (1-) categories is a very active research area and
  has provided new examples and led to the development of new invariants an
 d tools to understand these categories. \n\nIn this talk\, we will present
  a parametrization of multifusion 2-categories in terms of lower categoric
 al data\, involving braided fusion categories\, group theory\, and cohomol
 ogical data. If time allows\, we will also show some applications of this 
 result. This is a joint work in with T. Décoppet\, T. Johnson-Freyd\, P. 
 Huston\, D. Nikshych\, D. Penneys\, D. Reutter\, and M. Yu.\n
