Light-cone field theory, maximal supersymmetric theories and E7 (7) in light-cone superspace

No table of content available

• In this lecture I describe the light-cone formulation of quantum field theories especially the maximally supersymmetric ones. This is a formalism in which we keep only the physical degrees of freedom for both bosons and fermions. I show how N = 4 Yang-Mills Theory and N = 8 supergravity come out very naturally and that they look very much alike. I finally show how to implement the E7(7)symmetry for the supergravity theory. The new feature in this formulation is that all fields of the supermultiplet including the graviton transform under E7(7).
