Abstract
An algorithm is given for the calculation of higher-order corrections to the cut vertices and their coefficient functions of deep-inelastic and annihilation processes in the model field theory . The introduction of covariant phase-space variables renders the calculation simple and elucidates the relations between the deep-inelastic and annihilation structure functions.
