NLS孤波线性化算子的谱

Spectra of Linearized Operators for NLS Solitary Waves

Shu-Ming Chang, Stephen Gustafson, Kenji Nakanishi, Tai-Peng Tsai

摘要:

具有聚焦幂非线性项的非线性薛定谔方程存在孤波解。这些孤波周围的线性化算子的谱与孤波的稳定性以及(NLS)解的长时间动力学密切相关。我们研究这些光谱的详细,分析和数值。

英文摘要:

Nonlinear Schrödinger (NLS) equations with focusing power nonlinearities have solitary wave solutions. The spectra of the linearized operators around these solitary waves are intimately connected to stability properties of the solitary waves, and to the long-time dynamics of solutions of (NLS). We study these spectra in detail, both analytically and numerically.
