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 the behavior of the ground state energy under weak perturbation of critical quasilinear operators in $R^{N}$

Ujjal Das, Hynek Kovařík, Yehuda Pinchover

We consider a critical quasilinear operator $- Δ_{p} u + V ∣ u ∣^{p - 2} u$ in $R^{N}$ perturbed by a weakly coupled potential. For $N > p$ , we find the leading asymptotic of the lowest…
