On the derivation of bounds for the ladder graphs of a scattering amplitude
Description
The derivation of exact upper and lower bounds for the sum of scalar ladder graphs is described in detail. The bounds are consistent with Regge behaviour. The sum of ladder graphs diverges if the coupling constant is large. This divergence occurs as well in the gphi3 theory in four space-time dimensions as in the gphi4 theory in two dimensions. (Auth.)
