Asymptotic stability and completeness in the energy space for nonlinear Schrödinger equations with small solitary waves. (English) Zbl 1072.35167

Small in \(H^1\) solutions are decomposed into solitary and dispersive waves. It is shown that as \(t \rightarrow \infty\), the solitary wave component converges to a fixed solitary wave, and the dispersive component converges strongly in \(H^1\) to a solution of the free Schrödinger equation.
