Abstract
The study of the partial-wave dispersion relation (PWDR) is continued, being extended to the relativistic problem in the presence of inelasticity. Less restrictive sufficient conditions on the left-hand-cut discontinuity $\ensuremath{\Delta}T$ are obtained to guarantee a solution of the PWDR problem when $\ensuremath{\Delta}T$ has both positive and negative parts. The effect of Castillejo-Dalitz-Dyson poles on solutions is also discussed.
