DESCRIPTION:Title: <a href="https://researchseminars.org/talk/nhetc/15/">O
 n topological boundary conditions in 2+1d TQFT</a>\nby Shu-Heng Shao (YITP
 \, Stony Brook University) as part of NHETC Seminar\n\n\nAbstract\nA 2+1-d
 imensional topological quantum field theory (TQFT) may or may not admit to
 pological (gapped) boundary conditions. In this talk\, we consider obstruc
 tions to the existence of a topological boundary condition from the "highe
 r" central charges\, which have been introduced recently in the math liter
 ature. In terms of these new obstructions\, we identify necessary and suff
 icient conditions for the existence of a topological boundary in the case 
 of bosonic\, Abelian TQFTs\, providing an alternative to the identificatio
 n of a Lagrangian subgroup. Our proof relies on general aspects of gauging
  generalized global symmetries.\n
