Query: On a positivity preservation property for Schr\"odinger operators on
  Riemannian manifolds   We study a positivity preservation property for Schr\"odinger operators with
singular potential on geodesically complete Riemannian manifolds with
non-negative Ricci curvature. We apply this property to the question of
self-adjointness of the maximal realization of the corresponding operator.
