Deformed Virasoro algebras in supersymmetric gauge theories

by Fabrizio Nieri

Description
The Alday-Gaiotto-Tachikawa (AGT) correspondence allows a wide class of 4d supersymmetric gauge theories to be studied in a dual 2d CFT. In particular, the gauge theory partition function is identified with a 2d CFT correlator. In this talk I will discuss how the AGT correspondence can be extended to certain 5d and 6dsupersymmetric gauge theories, in which case the dual symmetry algebras are trigonometric or elliptic deformations of the Virasoro algebra.
