| dc.description.abstract | Using a generalization of the moment problem and the extremal properties of spectral measures corresponding to the self-adjoint extensions of a regular symmetric operator, we study point mass perturbations of spectral measures. We obtain general results for a wide class of operators and apply them to the analysis of point mass perturbations of spectral measures pertaining to Bessel and generalized Schrödinger operators. | |
