Essential self-adjointness of non-semibounded Schrödinger operators on infinite graphs
Ognjen Milatovic
We work in the setting of infinite, not necessarily locally finite, weighted graphs. We give a sufficient condition for the essential self-adjointness of (discrete) Schrödinger op…

On two properties of positively perturbed discrete Schrödinger operators
Ognjen Milatovic
We show that if we start from a symmetric lower semi-bounded Schrödinger operator on finitely supported functions on a discrete weighted graph (satisfying certain co…
