DESCRIPTION:Title: <a href="https://researchseminars.org/talk/nhetc/51/">N
 on-invertible symmetry and higher representation theory</a>\nby Matthew Bu
 llimore (Durham University) as part of NHETC Seminar\n\n\nAbstract\nThe pa
 st year has seen an explosion in constructions of non-invertible symmetrie
 s in quantum field theories in dimension greater than two\, such as gaugin
 g discrete symmetries with mixed ’t Hooft anomalies\, gauging non-normal
  subgroups of discrete symmetries\, higher gauging and condensations\, and
  duality defects. I’ll present a common framework for such constructions
  based on higher representation theory\, which describes higher dimensiona
 l analogues of topological Wilson lines. Based on joint work with Thomas B
 artsch\, Andrea Ferrari and Jamie Pearson.\n
