  The complete UV-divergent contribution to the one-loop 1PI four-point
function of Yang-Mills theory in the light-cone gauge is computed in this
paper. The formidable UV-divergent contributions arising from each four-point
Feynman diagram yield a succinct final result which contains nonlocal terms as
expected. These nonlocal contributions are consistent with gauge symmetry, and
correspond to a nonlocal renormalization of the wave function. Renormalization
of Yang-Mills theory in the light-cone gauge is thus shown explicitly at the
one-loop level.
