| Abstract: | An effective algorithm is provided for determining the number of negative eigenvalues of a one-dimensional Schrödinger operator with point interactions in terms of the intensities and the distances between the interactions. |
| Keywords: | continued fractions negative eigenvalues number of negative eigenvalues point interactions Schrö dinger operators |
