DESCRIPTION:Title: <a href="https://researchseminars.org/talk/WHCGP/28/">2
 -Group Global Symmetry in Quantum Field Theory</a>\nby Thomas Dumitrescu (
 UCLA) as part of Western Hemisphere colloquium on geometry and physics\n\n
 \nAbstract\nHigher-form generalizations of global symmetries play an impor
 tant role in Quantum Field Theory (QFT). In general\, symmetries of differ
 ent form degrees need not be independent\; instead\, they can form a highe
 r group. In this talk I will illustrate this phenomenon by explaining why 
 many simple Lagrangian QFTs in four and six dimensions enjoy 2-group globa
 l symmetries. I will then apply this understanding to deduce new general r
 esults about (typically non-Lagrangian) SCFTs in six dimensions.\n
