DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TQFT/44/">Qu
 inn Finite Total Homotopy TQFT as a once-extended TQFT</a>\nby João Faria
  Martins (University of Leeds) as part of Topological Quantum Field Theory
  Club (IST\, Lisbon)\n\n\nAbstract\nQuinn Finite Total Homotopy TQFT is a 
 TQFT that works in any dimension and that depends on the choice of a homot
 opy finite space $B$ (e.g. $B$ can be the classifying space of a finite gr
 oup or of a finite 2-group).  I will report on ongoing joint work with Tim
  Porter on once-extended versions of Quinn Finite total homotopy TQFT\, an
 d I will show how to compute them for the case when $B$ is the classifying
  space of a finite strict omega-groupoid (represented by a crossed complex
 ).\n\nSome stages of this work were financed by the Leverhulme trust resea
 rch project grant: Emergent Physics From Lattice Models of Higher Gauge Th
 eory.\n
