Spectral Theory for Sturm-Liouville operators with measure potentials through Otelbaev's function
Robert Fulsche, Medet Nursultanov
We investigate the spectral properties of Sturm-Liouville operators with measure potentials. We obtain two-sided estimates for the spectral distribution function of the eigenvalues…
