SUMMARY:Congkao Wen\, Queen Mary\, London - The positive orthogonal Grassma
 nnian and scattering amplitudes in ABJM
DESCRIPTION:The positive orthogonal Grassmannian and scattering amplitudes 
 in ABJM\nI will talk about the positive orthogonal Grassmannian and its co
 nnection to scattering amplitudes in ABJM theory via on-shell diagrams. Th
 e on-shell diagrams can be characterized by permutation\, which is the inv
 ariant information under equivalence moves. The functional map that arises
  from the moves satisfies the tetrahedron equations by Zamolodchikov\, imp
 lying (2+1)-dimensional integrability. I will also present the solution to
  the BCFW recursion relation for loop amplitudes in ABJM theory\, to all l
 oop\, four and six-point amplitudes can always be written in a dLog form.\
