摘要：

The light-cone gauge allows one to single out a set of transverse fields (TF), whose Green functions are free from UV divergences in SYM N=4. Green functions with external lines involving the remaining fields do instead exhibit divergences: indeed those fields can be expressed, by solving their equations of motion, as composite operators in terms of transverse fields. A set of exact identities (bridge identities) automatically realize their insertions in a path-integral formulation.
