A resonance in phonons scattering off a kink in the absence of a Peierls-Nabarro potential
Danial Saadatmand, Arpine Piloyan, David Amundsen +1
We investigate the interaction of small-amplitude waves called phonons, with an initially static kink in an exceptional discretization of the model that is free of the Peierl…

Radial positive solutions for mixed local and nonlocal supercritical Neumann problem
David Amundsen, Abbas Moameni, Remi Yvant Temgoua
In this paper, we establish the existence of positive non-decreasing radial solutions for a nonlinear mixed local and nonlocal Neumann problem in the ball. No growth assumption on…
