摘要研究了强迫NLS/Lugiato-Lefever模型在直线上的Barashenkov-Bogdan-Zhanlav孤子u±.虽然u+的不稳定性是在原始论文中建立的,[3],但u−的类似问题只是在理论上和数值上考虑的。我们严格地分析了u−在各种参数下的稳定性。特别地,我们证明了u−对于小泵浦强度h是光谱稳定的。此外,u−保持谱稳定,直到一对负Krein签名的中性本征值遇到另一对本征值,这对本征值从连续谱的边缘发出,[1,2,3]。碰撞后,不稳定性在以前的工作中被证实和数值观察到,[3]。
Abstract The Barashenkov-Bogdan-Zhanlav solitons u±for the forced NLS/Lugiato-Lefever model on the line are considered. While the instability of u+ was established in the original paper,[3], the analogous question for u− was only considered heuristically and numerically. We rigorously analyze the stability of u− in the various regime of the parameters. In particular, we show that u− is spectrally stable for small pump strength h. Moreover, u− remains spectrally stable until a pair of neutral eigenvalues of negative Krein signature hits another pair of eigenvalues, which has emanated from the edge of the continuous spectrum,[1, 2, 3]. After the collision, an instability is conjectured and numerically observed in previous works,[3].
