4d/2d duality and class S theory Arakawa, Tomoyuki


Rastelli et. al have constructed a map from 4d $N=2$ SCFTs to VOAs in such a way that the Schur index of a 4d $N=2$ SCFT coincides with the character of the corresponding VOA. Later, Rastelli and Beem have further conjectured that the Higgs branch of a 4d $N=2$ SCFT should coincide with the associated variety of the corresponding VOA. In my talk we confirm the conjecture of Rastelli and Beem for the theory of class S.
