NONLOCALITIES IN-FIELD THEORY

It has been known since the early 1980's that the computation of light -cone gauge Feynman integrals in the n(mu) prescription yields both l ocal and nonlocal ultraviolet divergences. Nevertheless, it was recent ly claimed that the nonlocal contributions to the Yang-Mills vacuum po larization tensor arise from application of the decomposition formula [q.n(q + p).n]-1 = (p.n)-1{-[(q + p).n]-1 +(q.n)-1}, p.n not-equal 0. The purpose of this paper is to show that nonlocal ultraviolet diverge nces automatically appear in light-cone gauge Feynman integrals define d by the n(mu) prescription, regardless whether the above decompositi on formula is employed or not.
