Summary
General subtraction procedures for many-body scattering equations are developed which allow one to separate different contributions to the fullN-body dynamics and to treat them independently in different nested sets of equations. Compact matrix subtraction procedures for both two-body connected-kernel and highly-connected-kernel equations are presented. We explicitly show how the original complicated labelling structure of two-body connected equations drastically reduces itself upon the selection of few dominant clusters or channels.
Riassunto
Nell’àmbito della teoria dello scattering a molti corpi si studiano alcuni procedimenti generali di sottrazione che permettono d’isolare contributi di natura diversa nelle equazioni dinamiche e di trattarli indipendentemente mediante equazioni che vanno inserite le une nelle altre. Si applicano tali procedimenti, in forma compatta matriciale, sia ad equazioni con connessione a due corpi sia ad equazioni altamente connesse. Si dimostra esplicitamente come la struttura complessa delle equazioni originali con connessione a due corpi si semplifichi drasticamente per effetto della selezione di pochi cluster o canali dominanti.
