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 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…
