DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TQFT/132/">C
 FT/TFT correspondence beyond semisimplicity</a>\nby Aaron Hofer (Universit
 y of Hamburg) as part of Topological Quantum Field Theory Club (IST\, Lisb
 on)\n\n\nAbstract\nSince the 1980s\, it has been well known that there is 
 a close relationship between two-dimensional conformal field theories and 
 three-dimensional topological field theories. This CFT/TFT correspondence 
 provides a tractable example of holography as well as a first example of t
 he symmetry TFT framework.\n\nThe Fuchs-Runkel-Schweigert construction is 
 a mathematically precise incarnation of this correspondence and provides a
  rigorous construction of correlators for rational CFTs using 3D TFTs of R
 eshetikhin-Turaev type. In this talk\, I will review the FRS construction 
 and explain how it can be generalized to non-rational CFTs using the non-s
 emisimple 3D TFTs of De Renzi\, Gainutdinov\, Geer\, Patureau-Mirand\, and
  Runkel.\n
