| Abstract: | We employ a Birman-Schwinger type analysis to derive estimates on the number of bound-states of certainN-body systems with threshold-energy  =inf  ess(H) supposed to be zero. For many-body systems without any substructure we show that eigenvalues of the Schrödinger operatorH absorbed at  =0 are in the point-spectrum ofH. Furthermore we characterize a multiparticle equivalent of the Efimov effect. |
