Abstract:
Sufficient conditions are obtained for the discrete spectrum of the energy operator of an n-particle
system to be finite in the space of functions of given permutational and rotational
symmetry. It is shown that under the same conditions the boundary of the continuous speetrum
cannot be an eigenvalue of infinite multiplicity. For application of the basic theorem,
the etgenvatues of the Schrödinger operator are investigated as functions of the coupling
constant.
