1-form symmetries of 4d N=2 class S theories

We determine the 1-form symmetry group for any 4d $\mathcal{N}$ = 2 class S theory constructed by compactifying a 6d $\mathcal{N}$ =(2,0) SCFT on a Riemann surface with arbitrary regular untwisted and twisted punctures. The 6d theory has a group of mutually non-local dimension-2 surface operators, m...
