Functional directed acyclical graphs for scattering amplitudes in perturbation theory
Abstract I describe a mathematical framework for the efficient processing of the very large sets of Feynman diagrams contributing to the scattering of many particles. I reexpress the established numerical methods for the recursive construction of scattering elements as operations on compact abstract...
