Asymptotic completeness of \(N\)-particle long-range scattering. (English) Zbl 0811.35091
The authors prove asymptotic completeness for \(N\)-particle long-range systems with potential at infinity with a power of \(| x |\) of order greater or equal to \(1 - 2^{-N-2}\). Asymptotic clustering is used to reduce the problem involving an \((N+1)\)-particle Schrödinger operator to that involving a time-dependent operator.
Subspaces of balistic and subbalistic propagation are characterized in terms of singular sets for (or the spectra of) appropriate asymptotic observables.
