Abstract
A technique introduced by Symanzik is used to derive a series of equations obeyed order by order in perturbation theory by the structure functions and entering the cross section for inelastic electron scattering. These equations relate the , , and coupling-constant dependence of and in a manner reminiscent of the renormalization-group results of Gell-Mann and Low. The equations are used to compute the leading logarithmic contribution to in a theory of fermions coupled to pseudoscalar particles and a theory of fermions coupled to vector particles.
