Properties of solutions forN-body Yakubovskii–Faddeev equations

Abstract
We give a revised presentation of the Yakubovskii–Faddeev formalism based on a systematic study of the N‐body system chain structure. Completeness properties of the corresponding equations in differential form are considered. The expressions of physical and spurious solutions are given in terms of the N‐body asymptotic partition Hamiltonians eigenvectors.
