I am looking for notes and papers that treat the N=4 D=4 Super Yang Mills theory, starting from an introductory level.
I have been using different notes so far (some mentioned in my previous question), but most of the notes I have focus on other kinds of supersymmetric theories.
My main interest in this subject is to eventually understand S duality and on-shell diagrams.
Please feel free to include advanced articles pertaining to the subject. It would be nice to have a compilation of such articles.
