The assumptions and results of recent work by Lipatov and others on the behavior of perturbation theory at high orders are delineated and used in conjunction with the Callan-Symanzik equation. Some consequences related to Borel summability and scaling are obtained for gphi/sup 4/ field theory in four dimensions. Our main result is to show that the above work implies that for this theory a contradiction exists between Borel summability in which the Borel sum fully determines the Euclidean Green's functions in a fixed interval, 0 < g < epsilon, and the existence of a nontrivial ultraviolet-stable fixed point for 0 < g < infinity.
