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.
