Abstract

Abstract Non-abelian gauge hteories in the light-cone gauge (defined by the Mandelstam-Leibbrandt prescription) can have non-local counterterms. Nevertheless, the possible counter-terms are severely restricted by gauge-invariance. We detail the possible form of the counter-terms. This enables us to complete the proof of the finiteness of N = 4 SUSY, by showing that if all three- and higher-field counter-terms are zero, then the two-field ones are also zero.
