Abstract We show that the cone of non-negative distributional supersolutions is one dimensional for an operator − Δ + 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] .
