Summary
The Faddeev equations are exactly reduced to multichannel two-particle Lippmann-Schwinger-type equations, the kernel of which is the solution of Faddeev equations with two-particle potentials too weak to produce bound states. This suggests a scheme of successive approximations of which the separable approximation is the first.
Riassunto
Le equazioni di Faddeev sono ridotte esattamente ad equazioni del tipo di Lippmann-Schwinger per due particelle a molti canali; equazioni il cui nucleo è la soluzione delle equazioni di Faddeev con potenziali di due particelle troppo deboli per produrre stati legati. Tutto ciò suggerisce uno schema di approssimaziuoni successive di cui l'approssimazione separabile è la prima.
Резюме
Уравнения Фадеева точно приводятся к много-каналыным двухчастичным двухчастичным уравнениям, типа Липмана-Швингера, ядром которых является решение уравнений Фадеева с двух-частичными потенциалами, слишком слабыми, чтобы образовать связанные состояния. Это предполагает схему последователяных приближений, для которых отделяемое приближыние является первым.
