DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UCGEN/23/">T
 wo-dimensional extended HQFTs with arbitrary targets</a>\nby Kürşat Söz
 er (University of Lille) as part of UCGEN - Uluslararası Cebirsel GEometr
 i Neşesi\n\n\nAbstract\nInspired by theoretical physics\, topological qua
 ntum field theories (TQFTs) produce manifold invariants behaving well unde
 r gluing. Homotopy quantum field theories (HQFTs)\, introduced by Turaev\,
  generalize TQFTs to manifolds equipped with continuous maps to fixed targ
 et space. A different generalization of TQFTs is given by extended TQFTs w
 hich includes lower-dimensional manifolds utilizing higher categories. In 
 this talk\, we define and classify 2-dimensional extended HQFTs with arbit
 rary targets generalizing the earlier work on K(G\,1)-targets using the me
 thods introduced for TQFTs by Chris Schommer-Pries in 2009.\n
