关于NLS方程物理基态的轨道稳定性

On orbital stability of the physical ground states of the NLS equations

Yavdat Il'yasov

摘要:

证明了非线性薛定谔方程的物理基态的轨道稳定性结果,即基态集合包含在由Cazenave-Lions定理确定的轨道稳定的预定质量解集合中.我们应用非线性广义瑞利散射方法,该方法允许建立物理基态的质量$m$、频率$λ$和作用水平$S$的值之间的一一对应关系。

英文摘要:

We prove orbital stability result for physical ground states of a nonlinear Schrödinger (NLS) equation in the sense that the set of these ground states is contained in the set of prescribed mass solutions which is orbital stable by the Cazenave-Lions theorem. We apply the nonlinear generalized Rayleigh quotients method which allows establishing a one-to-one correspondence between the values of the mass $m$, the frequency $λ$, and the action level $S$ of the physical ground states.
