Abstract: (APS)
We show that the inverse propagator Γ(x) and the proper self-energy part Π(x) are positive for all x≠0. These results combined with some postulates on the sign or the decay of the vertex functions, in particular, on the decay rate for Γ(x), yield the absence of three-particle bound states and the existence of the scaling (Gell-Mann, Low, Wilson) limit for the φ4 interaction.- FIELD THEORY: CONSTRUCTIVE
