Superconformal Index, BPS Monodromy and Chiral Algebras

Sergio Cecotti, Jaewon Song, Cumrun Vafa +1

We show that specializations of the 4d $N = 2$ superconformal index labeled by an integer $N$ is given by $Tr M^{N}$ where $M$ is the Kontsevich-Soibe…

Higher S-dualities and Shephard-Todd groups

Sergio Cecotti, Michele Del Zotto

Seiberg and Witten have shown that in N=2 SQCD with $N_{f} = 2 N_{c} = 4$ the S-duality group PSL(2,Z) acts on the flavor charges, which are weights of Spin(8), by triality. There are other…

Galois covers of N=2 BPS spectra and quantum monodromy

Sergio Cecotti, Michele Del Zotto

The BPS spectrum of many 4d N=2 theories may be seen as the (categorical) Galois cover of the BPS spectrum of a different 4d N=2 model. The Galois group G acts as a physical symmet…
