Abstract: We investigate a Schrödinger operator $ - \Delta /2 + V$ in $ {R^d}\;(d \geq 3)$ with a potential $ V$ in the class $ {K_d}$ satisfying a similar Kato condition at infinity, and prove an equivalence theorem connecting various conditions on subcriticality, strong positivity and gaugeability of the operator.
