Description
A key challenge in the study of scattering amplitudes of $\mathcal{N}=4$ super-Yang-Mills theory is to understand their analytic structure. Symbols, a central tool in this topic, are known to contain particular cluster coordinates of $Gr(4,n)$ together with certain algebraic functions of cluster coordinates. In my talk, I will present an algorithm for computing symbol alphabets by solving matrix equations of the form $C \cdot Z = 0$ to relate parameterizations of certain $Gr(k,n)$ plabic graphs to functions on $Gr(m,n)$.
