Elliptic Hypergeometric Sum/Integral Transformations and Supersymmetric Lens Index
We prove a pair of transformation formulas for multivariate elliptic hypergeometric sum/integrals associated to the An and BCn root systems, generalising the formulas previously obtained by Rains. The sum/integrals are expressed in terms of the lens elliptic gamma function, a generalisation of the e...

Spiridonov, for their comments. We also thank the anonymous referees for helpful comments, which led us to use a change of variables to write the An transformation in a way where the right hand side of (3.5) is manifestly periodic in both the complex and integer variables. Particularly, the periodicity is necessary to allow the (mod 2r) and (mod r), in the balancing condition (3.1).

We prove a pair of transformation formulas for multivariate elliptic hypergeometric sum/integrals associated to the An and BCn root systems, generalising the formulas previously obtained by Rains. The sum/integrals are expressed in terms of the lens elliptic gamma function, a generalisation of the elliptic gamma function that depends on an additional integer variable, as well as a complex variable and two elliptic nomes. As an application of our results, we prove an equality between S¹×S³/Zr supersymmetric indices, for a pair of four-dimensional N=1 supersymmetric gauge theories related by Seiberg duality, with gauge groups SU(n+1) and Sp(2n). This provides one of the most elaborate checks of the Seiberg duality known to date. As another application of the An integral, we prove a star-star relation for a two-dimensional integrable lattice model of statistical mechanics, previously given by the second author.
