DESCRIPTION:Title: <a href="https://researchseminars.org/talk/WHCGP/35/">H
 igher central charges and gapped boundaries</a>\nby Zohar Komargodski (SCG
 P\, Stony Brook) as part of Western Hemisphere colloquium on geometry and 
 physics\n\n\nAbstract\nThe chiral central charge is a famous diagnostic of
  edge modes on the boundary of 2+1 dimensional topological phases. We show
  that many theories with a vanishing chiral central charge nevertheless ca
 nnot admit a gapped boundary. We define higher chiral central charges and 
 investigate their properties.\n
