Adjacency for scattering amplitudes from the Gröbner fan
Abstract Scattering amplitudes in planar N $$ \mathcal{N} $$ = 4 super Yang-Mills theory exhibit singularities which reflect various aspects of the cluster algebras associated to the Grassmannians Gr(4, n) and their tropical counterparts. Here we investigate the potential origins of such structures...
