Yangian Invariants and Cluster Adjacency in N=4 Yang-Mills
arXiv:1906.10682 · doi:10.1007/JHEP10(2019)099
Abstract
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 the Sklyanin Poisson bracket on Gr(4,n) to check numerous examples.
