On Schrödinger operators with multisingular inverse-square anisotropic potentials
Veronica Felli, Elsa M. Marchini, Susanna Terracini
We study positivity, localization of binding and essential self-adjointness properties of a class of Schroedinger operators with many anisotropic inverse square singularities, incl…
On the behavior of solutions to Schrödinger equations with dipole-type potentials near the singularity
Veronica Felli, Elsa M. Marchini, Susanna Terracini
Asymptotics of solutions to Schroedinger equations with singular dipole-type potentials is investigated. We evaluate the exact behavior near the singularity of solutions to ellipti…
On Schoedinger operators with multipolar inverse-square potentials
Veronica Felli, Elsa M. Marchini, Susanna Terracini
Positivity, essential self-adjointness, and spectral properties of a class of Schroedinger operators with multipolar inverse-square potentials are discussed. In particular a necess…
On Hopf's Lemma and the Strong Maximum Principle
S. Bertone, A. Cellina, E. M. Marchini
In this paper we consider Hopf's Lemma and the Strong Maximum Principle for supersolutions to a class of non elliptic equations. In particular we prove a sufficient condition for t…
