| Zusammenfassung: | Positivity, essential self-adjointness, and spectral properties of a class of
Schroedinger operators with multipolar inverse-square potentials are discussed.
In particular a necessary and sufficient condition on the masses of
singularities for the existence of at least a configuration of poles ensuring
the positivity of the associated quadratic form is established. |
