Dualities in superconformal gauge theory

We consider several observables in maximally supersymmetric gauge theory in four dimensions: correlation functions of gauge invariant operators, Wilson loops and scattering amplitudes. We show that there exist (un)expected duality relations between them, in the planar approximation and in a singular light-like limit. The duality reveals a hidden dynamical symmetry of the Yangian type.
