Existence of two-cluster threshold resonances and the \(N\)-body Efimov effect. (English) Zbl 1111.81146
J. Math. Phys. 46, No. 11, 112106, 12 p. (2005).
Summary: We prove the existence of two-cluster threshold resonances in \(N\)-body problems and study their perturbation by intercluster interactions. As application, we construct concrete examples based on Yukawa potentials for which the \(N\)-body Efimov effect happens with \(N\geqslant 4\).
