DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TQFT/160/">N
 ested cobordisms and TQFTs</a>\nby Maxine Calle (University of Pennsylvani
 a) as part of Topological Quantum Field Theory Club (IST\, Lisbon)\n\n\nAb
 stract\nA well-known folklore theorem classifies 2-dimensional topological
  quantum field theories (TQFTs) in terms of Frobenius algebras\, providing
  a unifying link between topology\, algebra\, and physics. In this talk\, 
 we explore what happens when the usual cobordism category is replaced by a
  category of nested cobordisms\, in which 2-dimensional surfaces are equip
 ped with embedded 1-dimensional submanifolds. We study symmetric monoidal 
 functors out of this category and the resulting algebraic structures they 
 encode. This talk is based on joint work with R. Hoekzema\, L. Murray\, N.
  Pacheco-Tallaj\, C. Rovi\, and S. Sridhar.\n\nPlease note the change of d
 ay and time!\n
