DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TQFT/117/">S
 tate spaces in TFT: Quivers and infinite particle algebras</a>\nby Gregor 
 Schaumann (University of Würzburg) as part of Topological Quantum Field T
 heory Club (IST\, Lisbon)\n\n\nAbstract\nA topological field theory (TFT) 
 with particles exhibits distinguished state spaces\, where the incoming an
 d outgoing particles match. These "endo-state spaces" occur naturally in p
 hysical applications and possess interesting mathematical structures: Ther
 e is a natural gauge action by conjugation and a natural stabilization map
 . We will show that the gauge action has a non-trivial orbit structure\, l
 eading to quiver moduli spaces\, and the stabilization map leads to a trea
 tment of infinite particle content and AF-algebras.\n\nThe talk will be ra
 ther introductory and assumes no knowledge of quivers or AF-algebras.\n
