竞争幂非线性薛定谔方程中大孤子的稳定性

Stability of Big Solitons in a Competitive Power Nonlinear Schrödinger Equation

Jian Zhang, Mengxue Bai

摘要:

通过引入并求解两个相关的约束变分问题和谱分析,找到了一种由给定质量确定非线性薛定谔方程孤子频率的方法,解决了归一化解中的一个公开问题.首次证明了具有竞争幂非线性项的非线性薛定谔方程存在依赖于频率的大孤子及其轨道稳定性。另外,利用稳定的大孤子构造了不同速度的多孤子。

英文摘要:

By introducing and solving two correlative constrained variational problems as well as spectrum analysis, an approach to fix soliton frequency from the prescribed mass for nonlinear Schrödinger equations is found, and an open problem in normalized solutions is answered. Then existence and orbital stability of big solitons depending on frequencies for nonlinear Schrödinger equation with competitive power nonlinearity is proved for the first time. In addition multi-solitons of the equation with different speeds are constructed by stable big solitons.
