The single-massless-particle poles in the connected functional lead to divergences in the path integral which must be regulated. The most satisfying situation would be to find a unique regulator which, in effect, truncated the connected functional to the one-particle-irreducible functional. Steps in this direction have recently been taken by several authors \[8-10\].",
