On the Proof of Parametric Dispersion Relations

Abstract
Parametric dispersion relations for the connected time-ordered Green's functions, conjectured by Nishijima on the basis of perturbation theory, are shown to exist for the special case of decay processes. Extension of the proof to the more interesting situations of scattering and production depends upon the possibility of continuing one or more of the energy variables to negative values.
