Stability of standing waves for all frequencies to nonlinear Schrödinger equations with potentials in one dimension

Noriyoshi Fukaya, Masahiro Ikeda, Hiroaki Kikuchi

In this paper, we study the orbital stability of standing waves for one-dimensional nonlinear Schrödinger equations with potentials. We show that the standing waves are orbitally s…

Traveling waves for a nonlinear Schrödinger system with quadratic interaction

Noriyoshi Fukaya, Masayuki Hayashi, Takahisa Inui

We study traveling wave solutions for a nonlinear Schrödinger system with quadratic interaction. For the non mass resonance case, the system has no Galilean symmetry, which is of p…
