Point mass perturbations of spectral measures

Rafael del Rio, Luis O. Silva, Julio H. Toloza

摘要:

利用矩问题的推广和正则对称算子自伴扩张对应的谱测度的极值性质,研究了谱测度的质点扰动.我们得到了广泛的一类运营商的一般结果,并将其应用到分析的质点扰动的频谱措施有关贝塞尔和广义薛定谔运营商。

英文摘要:

Using a generalization of the moment problem and the extremal properties of spectral measures corresponding to the selfadjoint 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.
