DESCRIPTION:[b]Speaker: Jamie Pearson[/b]\n(Durham) \n\n\n[b]Abstract:[/b]
  Recent studies on symmetries are often focused on those non-invertible s
 ymmetries that steer away from familiar (invertible) group-like structure
 s\, but in recent works (2408.13931) by M. Bullimore and myself\, we conj
 ecture that in fact all finite symmetries of oriented 3-dimensional QFTs 
 can be constructed by employing tools from group theory. In the first hal
 f of this talk we will review category-theoretic descriptions of non-inve
 rtible symmetries and how this data is closely related to that of higher-
 dimensional (symmetry) TFTs. In the latter half of the talk we will shift
  our focus to symmetries in 3d\, aiming to demonstrate a classification i
 n terms of the category of gapped/topological boundary conditions of 4-di
 mensional Dijkgraaf-Witten theory.
