DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TQFT/108/">O
 rbifold completion of 3-categories</a>\nby Nils Carqueville (University of
  Vienna) as part of Topological Quantum Field Theory Club (IST\, Lisbon)\n
 \n\nAbstract\nWe develop a general theory of 1-\, 2-\, and 3-dimensional "
 orbifold completion"\, to describe (generalised) orbifolds of topological 
 quantum field theories as well as all their defects. This can be viewed as
  the "oriented version" of condensation completion. We give a basic introd
 uction to TQFTs and their orbifolds\, and discuss applications which inclu
 de defect TQFTs for state sum models\, Reshethikin-Turaev and Crane-Yetter
  theory. This is joint work with Lukas Müller.\n
