The latter plays a crucial role in dispersion-theory approaches to coupled-channel systems that model final state interactions in QCD. A general spectral representation is established that is valid in the presence of anomalous thresholds, decaying particles or overlapping left-hand and right-hand cut structures as it occurs frequently in hadron physics. The results are illustrated at hand of ten specific processes Kategória publikačnej činnosti ADC Číslo archívnej kópie 33414 Katal.org.
