Criticality theory for Schrodinger operators with singular potential (vol 265, pg 3400, 2018)

[摘要] We show that the cone of non -negative distributional supersolutions is one dimensional for an operator - A + V with a locally integrable potential V satisfying property (1.1) below. As a consequence, we obtain a characterisation of critical/subcritical operators with potentials in a much larger class than considered in [1]. ? 2020 Elsevier Inc. All rights reserved.
