A Criterion for Singularities in Perturbation Theory

Journal of Mathematical Physics, 1962
A criterion is proposed to distinguish between the singular and nonsingular portions of the Landau surface on the physical sheet. The set of diagrams under consideration are those containing a single loop. A proof of the Mandelstam representation for the four-point function is given based on this criterion.
