Defect groups of class S $$ \mathcal{S} $$ theories from the Coulomb branch

Abstract We study the global forms of class S A N − 1 $$ \mathcal{S}\left[{A}_{N-1}\right] $$ 4d N $$ \mathcal{N} $$ = 2 theories by deriving their defect groups (charges of line operators up to screening by local operators) from Coulomb branch data. Specifically, we employ an explicit construction...
