Celestial dual superconformal symmetry, MHV amplitudes and differential equations

A bstract Celestial and momentum space amplitudes for massless particles are related to each other by a change of basis provided the Mellin transform. Therefore properties celestial have counterparts in vice versa. In this paper, we study avatar dual superconformal symmetry $$ \mathcal{N} N = 4 Yang-Mills theory. We also analyze various differential equations known be satisfied n -point tree-level MHV identify their origins.
