DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TQFT/32/">Bu
 lk-boundary correspondences with factorization algebras</a>\nby Owen Gwill
 iam (Univ. Massachusetts\, Amherst) as part of Topological Quantum Field T
 heory Club (IST\, Lisbon)\n\n\nAbstract\nFactorization algebras provide a 
 flexible language for describing the observables of a perturbative QFT\, a
 s shown in joint work with Kevin Costello. Those constructions extend to a
  manifold with boundary for a special class of theories. I will discuss wo
 rk with Eugene Rabinovich and Brian Williams that includes\, as an example
 \, a perturbative version of the correspondence between chiral ${\\rm U}(1
 )$ currents on a Riemann surface and abelian Chern-Simons theory on a bulk
  3-manifold\, but also includes a systematic higher dimensional version fo
 r higher abelian CS theory on an oriented smooth manifold of dimension $4n
 +3$ with boundary a complex manifold of complex dimension $2n+1$. Given ti
 me\, I will discuss how this framework leads to a concrete construction of
  the center of higher enveloping algebras of Lie algebras\, in work with G
 reg Ginot and Brian Williams.\n\nPLEASE NOTE THE UNUSUAL TIME!\n
