Compactification on the Ω-background and the AGT correspondence

It has been argued that the AGT correspondence originates from two ways to compactify the 6d (2,0) theory. One is compactification on a punctured Riemann surface, which produces 4d N = 2 supersymmetric gauge theory. The other is compactification on the Ω-background. I will discuss how the latter can produce Liouville theory and its generalizations. The basic strategy is to consider another kind of compactification using two cigar-like manifolds.
