Symbol alphabets from plabic graphs
Abstract Symbol alphabets of n-particle amplitudes in N $$ \mathcal{N} $$ = 4 super-Yang-Mills theory are known to contain certain cluster variables of Gr(4, n) as well as certain algebraic functions of cluster variables. In this paper we suggest an algorithm for computing these symbol alphabets fro...
