“Positive Grassmannians and the Geometry of Wilson Loop diagrams”
In this talk, I introduce a family of diagrams, called Wilson loop diagrams, of physical significance in SYM N=4 theory. There is strong evidence that these diagrams should define a submanifold of the positive Grassmannian Gr≥0(k,n), with k and n determined by the diagram. I present a map from these diagrams to the positive Grasmannians, and explore the geometry of the Wilson Loop diagrams.
