Orbital instability of standing waves for the quadratic–cubic Klein-Gordon–Schrödinger system

Abstract

We consider the Klein-Gordon–Schrödinger system with quadratic and cubic interactions. Smooth curves of periodic- and solitary-wave solutions are obtained via the implicit function theorem. Orbital instability of such waves is then established.
