Query: Yangian Symmetry for the Action of Planar N=4 Super Yang-Mills and N=6
  Super Chern-Simons Theories   In this article we establish the notion of classical Yangian symmetry for
planar N=4 supersymmetric Yang-Mills theory and for related planar gauge
theories. After revisiting Yangian invariance for the equations of motion, we
describe how the bi-local generators act on the action of the model such that
the latter becomes exactly invariant. In particular, we elaborate on the
relevance of the planar limit and how to act non-linearly with bi-local
generators on the cyclic action.
