On Schrödinger Operators with Multipolar Inverse-square Potentials
نویسنده
چکیده
Positivity, essential self-adjointness, and spectral properties of a class of Schrödinger 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.

On Schrödinger Operators with Multisingular Inverse-square Anisotropic Potentials
We study positivity, localization of binding and essential self-adjointness properties of a class of Schrödinger operators with many anisotropic inverse square singularities, including the case of multiple dipole potentials.
متن کاملBound States of Discrete Schrödinger Operators with Super-critical Inverse Square Potentials
We consider discrete one-dimensional Schrödinger operators whose potentials decay asymptotically like an inverse square. In the super-critical case, where there are infinitely many discrete eigenvalues, we compute precise asymptotics of the number of eigenvalues below a given energy E as this energy tends to the bottom of the essential spectrum.
متن کاملInverse Scattering Theory for One-dimensional Schrödinger Operators with Steplike Periodic Potentials
We develop direct and inverse scattering theory for one-dimensional Schrödinger operators with steplike potentials which are asymptotically close to different finite-gap periodic potentials on different half-axes. We give a complete characterization of the scattering data, which allow unique solvability of the inverse scattering problem in the class of perturbations with finite second moment.

v > 0 in R \ {a1, . . . , ak}, where N ≥ 3, k ∈ N, hi ∈ C(S), (a1, a2, . . . , ak) ∈ R , ai 6= aj for i 6= j, and 2 = 2N N−2 is the critical Sobolev exponent. The interest in such a class of equations arises in nonrelativistic molecular physics. Inverse square potentials with anisotropic coupling terms turn out to describe the interaction between electric charges and dipole moments of molecules...
