Negative eigenvalue estimates for the 1D Schr{ö}dinger operator with measure-potential

Robert Fulsche, Medet Nursultanov, Grigori Rozenblum

We investigate the negative part of the spectrum of the operator $-{\partial }^2-\mu$ on $L^2(\mathbb{R})$, where a locally finite Radon measure $\mu \ge 0$ is serving as a potential. We…
