摘要: In this paper we review recent results on symmetries in N=4 super Yang-Mills theory. Symmetries are of invaluable help studying and constraining the scattering amplitudes, there has been a lot progress years concerning topic. It realised that ordinary superconformal symmetry is not full There indeed dual symmetry, together they form Yangian structure, pointing to underlying integrability Here give an overview algebra its action at tree loop level. This article invited for Focus Issue "Gauge/String Duality 2011" Advances High Energy Physics.
