Weak Separation, Positivity and Extremal Yangian Invariants
Luke Lippstreu, Jorge Mago, Marcus Spradlin +1
We classify all positive n-particle N^kMHV Yangian invariants in N=4 Yang-Mills theory with n=5k, which we call extremal because none exist for n>5k. We show that this problem is e…

Yangian Invariants and Cluster Adjacency in N=4 Yang-Mills
Jorge Mago, Anders Schreiber, Marcus Spradlin +1
We conjecture that every rational Yangian invariant in N=4 SYM theory satisfies a recently introduced notion of cluster adjacency. We provide evidence for this conjecture by using…
