$M$耦合半线性薛定谔方程系统基态的稳定性

Stability of ground-states for a system of $M$ coupled semilinear Schrödinger equations

Simão Correia

摘要:

本文研究了具有幂型非线性项和耦合项的$M$耦合半线性薛定谔方程系统的基态稳定性。我们的结果是单方程理论的推广,并简化了这类结果的技巧。根据非线性的功率,我们可以观察到稳定性,不稳定性和弱不稳定性。我们还获得了三个不同的类的束缚态,这是一个特殊的功能的$M\ge2$的情况下的结果。

英文摘要:

We focus on the study of the stability properties of ground-states for the system of $M$ coupled semilinear Schrödinger equations with power-type nonlinearities and couplings. Our results are generalizations of the theory for the single equation and the technique for this kind of results is simplified. Depending on the power of the nonlinearity, we may observe stability, instability and weak instability. We also obtain results for three distinct classes of bound-states, which is a special feature of the $M\ge2$ case.
