Abstract

We employ the recently discovered Hopf algebra structure underlying perturb ative quantum field theory to derive iterated integral representations for Feynman diagrams. We give two applications: to massless Yukawa theory and q uantum electrodynamics in four dimensions. [S0556-2821(99)05020-1].
