Instability of standing waves for a system of nonlinear Schrödinger equations in a degenerate case (1602.01201v1)
Published 3 Feb 2016 in math.AP
Abstract: We study a system of nonlinear Schr\"odinger equations with cubic interactions in one space dimension. The orbital stability and instability of semitrivial standing wave solutions are studied for both non-degenerate and degenerate cases.
