Description
Dimensional reduction often implies non-trivial connections between field theories in different dimensions. A well-known example is the AGT (Alday-Gaiotto-Tachikawa) type relation that connects partition functions of different theories sharing a common higher dimensional ancestor. In this talk we shall exploit this relation to study the compactification of the 4d H0 SCFT on Riemann surfaces to get 2d (2,2) theories. Specifically, we shall argue for a 2d/2d unitary/non-unitary correspondence of AGT type between the resulting 2d theories and the Lee-Yang minimal model. We use this to identify the resulting 2d theories for certain choices of the Riemann surfaces, and test them with a variety of consistency checks.
