The question of including relativistic effects appeared together with the consideration of the decay amplitude in the framework of the dispersion technique. The relativistic dispersion description of amplitudes always takes into account processes connected with the investigated reaction by the unitarity condition or by virtual transitions; in the case of three-particle processes they are, as a rule, those where other many-particle states and resonances are produc 606 $aParticles (Nuclear physics) 606 $aDispersion relations 608 $aElectronic books. 615 0$aParticles (Nuclear physics) 615 0$aDispersion relations. 676 $a539.725 701 $aAnisovich$b A.
