where φn (Q )≡ φλ n1 (qλ ⅛)2 n 2 (q 2 y..q>NNN (qN ) and n ≡( nι, n 2,∙∙∙, nN ) runs through all
possible eigenstate combinations. Inserting eq. (4) into eq. (2) and performing the
standard eigenfunction separation (e∙g∙ by taking a scalar product), we obtain the system
of equations for ψn (ξ) , which is equivalent to the starting existence equation:
[ho (ξ) + V00 (ξ)] ψ0 (ξ ) + Σ V)n (ξ ψ (ξ ) = ηψθ (ξ ) , (5a)

and we have separated the equation for ψ0 (ξ) describing the generalised “ground state”
of system elements, i∙ e∙ the state with minimum energy and complexity∙
Now we try to “solve” eqs∙ (5) by expressing ψn (ξ) through ψ0 (ξ) from eqs∙
(5b) with the help of the standard Green function and substituting the result into eq∙
(5a), which gives the effective existence equation for ψ0 (ξ) [9-13]:
h 0 (ξ)ψ0 (ξ) + Veff (ξ; ηψ0 (ξ) = ηψ 0 (ξ), (8)
where the effective (interaction) potential (EP), Veff (ξ; η), is obtained as
Viff (ξ; η ) = V00 (ξ) + V (ξη), V(ξ; η )ψ> (ξ)= ∫ dξV (ξ,ξ,; η (ξ'),

The eigenfunctions {ψ0i (ξ)} and eigenvalues {ηi } found from eq∙ (8) are used
to obtain other state-function components:
