Recently a prescription to compute the four-dimensional N = 2 superconformal index in the presence of certain BPS surface defects has been given. These surface defects are labelled by symmetric representations of SU(N). In the present paper we give a... Read More about Surface defects, the superconformal index and q-deformed Yang-Mills.

On S-duality of the superconformal index on lens spaces and 2d TQFT (2013)

We consider the 4d superconformal index for N=2 gauge theories on S 1 × L(r, 1), where L(r, 1) is a Lens space. We focus on a one-parameter slice of the three-dimensional fugacity space and in that sector we show S-duality. We do so by rewriting the...
