Abstract: For the Schrödinger operator whose potential is rapidly decreasing at infinity, an estimate for the number of eigenvalues is given, thus answering a question going back to Gelfand. The case of three-dimensional configuration space is chosen for simplicity of presentation; all the results formulated in the paper can be extended to an arbitrary number of degrees of freedom.
Bibliography: 19 titles.
Keywords: Schrödinger operator, Fredholm determinant, total multiplicity of eigenvalues.
