Global form of flavor symmetry groups in 4d N=2 theories of class S

Global form of flavor symmetry groups in 4d N=2 theories of class S

We provide a systematic method to deduce the global form of flavor symmetry groups in 4d N=2 theories obtained by compactifying 6d N=(2,0) superconformal field theories (SCFTs) on a Riemann surface carrying regular punctures and possibly outer-automorphism twist lines. Apriori, this method only d...
