Abstract
A lower bound on the contribution of 2nth-order perturbation theory to the two-point function for 0D<4 (D is the number of spatial dimensions) is given; for zero mass (Pomeranchuk) the lower bound is cng2n(n!)3D2, while for nonzero mass (intercept below 1) it is cng2nn!, where g is the coupling constant and c is an appropriate constant. Subtraction of divergences or restricting ourselves to skeleton diagrams does not change the type of behavior of these terms.
