Strictly positive optimal Hardy weights on manifolds and graphs via Green potential
Ujjal Das, Matthias Keller, Yehuda Pinchover
Consider a subcritical functional associated with a -Schrödinger operator defined on a domain in noncompact Riemannian manifold. Employing the supersolution construction…
On the Landis Conjecture for Positive Quasi-linear Operators on Graphs
Ujjal Das, Matthias Keller, Yehuda Pinchover
We prove a Landis type unique continuation result for positive quasi-linear operators on graphs. Specifically, we give decay criteria that ensures when a harmonic function for a po…
On Landis' conjecture for positive Schrödinger operators on graphs
Ujjal Das, Matthias Keller, Yehuda Pinchover
In this note we study the Landis conjecture for positive Schrödin\-ger operators on graphs. More precisely, we prove a Landis-type result in the form of a decay criterion that ensu…
The space of Hardy-weights for quasilinear operators on discrete graphs
Ujjal Das, Matthias Keller, Yehuda Pinchover
We study Hardy inequalities for -Schrödinger operators on general weighted graphs. Specifically, we prove a Maz'ya-type result, where we characterize the space of Hardy weights…
