Title: Toda theory from six dimensions 

Abstract: I will give a constructive derivation of the Alday-Gaiotto-Tachikawa correspondence. The correspondence relates certain observables of strongly interacting 4d quantum field theories with 8 supercharges to correlation functions in 2d Toda conformal field theory. The 4d theories in question are obtained by compactification of the 6d (2,0) theory on a Riemann surface, and the Toda theory lives on that Riemann surface. The derivation I will give involves reduction of the (2,0) theory on the 4-sphere to directly obtain the Toda theory.
