From Orthogonal Grassmanian to Three-algebra
Seminar Room 1, Newton Institute
The leading singularities of ABJM amplitudes are given by the residues of an Orthogonal Grassmanian. I will discuss how this information controls the multi-loop amplitude, revealing an interesting relation between 4D N=4 SYM and ABJM. The behavior of the residues under complex deformation encodes, to the first order, the recent kinematic/three-algebra duality.
