A generalization of the radiation condition of Sommerfeld for $$N$$-body Schrödinger operators. (English) Zbl 0804.35113
The author proposes a new formulation of the radiation condition for the $$N$$-body problem. Because of the presence of many channels, the resolvent of the $$N$$-body Schrödinger operator does not behave like that of the Laplacian. The proof of the main theorem consists in introducing the algebraic framework which is inspired by the classical idea of integration by parts and the algebra of pseudo-differential operators.
