Povzner-Wienholtz-type theorems for Sturm-Liouville operators with singular coefficients

Andrii Goriunov, Vladimir Mikhailets, Volodymyr Molyboga

We introduce and investigate symmetric operators $L_{0}$ associated in the complex Hilbert space $L^{2} (R)$ with a formal differential expression \[l[u] :=-(pu')'+qu + i((ru)'…

Schrödinger operators with measure-valued potentials: semiboundedness and spectrum

Vladimir Mikhailets, Volodymyr Molyboga

We study the 1-D Schrödinger operators in Hilbert space $L^{2} (R)$ with real-valued Radon measure $q^{'} (x)$ , $q \in BV_{l oc} (R)$ as potentials. New sufficie…
