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…
