光纤中暗孤子传输理论 总被引:1,自引:0,他引:1
本文基于引入的特定辅助谱参数ζ,避开了从原谱参数λ出发由于双值函数的出现不得不引入Riemann面造成的复杂,不仅简明地再导出了Zakharov和Shabat关于NLS方程在边值非0时求解的反散射方法,而且进一步导出了暗的多孤子解的显式,Jost解的完备集合与系统的Hamilton理论。简单地解决了解的常数相引起的问题。最后,对含修正项的NLS方程在边值非0时建立有效的微扰理论所遇到的困难进行了讨论。 相似文献

COMPLETENESS OF THE JOST SOLUTIONS IN THE CASE OF THE NLS+ EQUATION WITH NONVANISHING BOUNDARY CONDITION 下载免费PDF全文
In the case of the NLS+ equation with nonvanishing boundary condition, a complete set of the Jost solutions is chosen, and its completeness is shown by means of the Marchenko inverse scattering equation. 相似文献

For the NLS+ equation under nonvanishing boundary condition, to avoid complexity due to Riemann surface, required for double-valued function of the usual spectral parameter, starting from a particular auxiliary spectral parameter, a special inverse scattering method is systematically developed, and explicit expressions of the general multi-soliton solutions are successfully obtained. Asymptotic behaviors of the muiti-soliton solutions, additional displacement of center and additional phase shift of the peak are derived. When the boundary value approaches zero, all the formulas become the known ones naturally. 相似文献

对求孤子解的Z-S反散射方程组,给出了它的等价的不可约形式。在求N-孤子解时,Z-S方程组由2N个线性代数方程组成,求解手续就是计算一个2N×2N矩阵之逆。而本文所得的它的不可约形式,是由N个线性代数方程组成的,求解只需计算一个N×N矩阵之逆,从而使计算量大大缩小。文未给出求两孤子解和呼吸子解的实际的简单计算和结果。 相似文献

从扩充的含零点的黎曼问题方法的基本方程,利用规范变换建立了求解铁磁链方程的完整的线性代数方程组。它将通常的反散射法的Takatajan方程组作为特例(λ_j限于上半平面)包括在内。对λ_j任意时将给出新的正则解。 相似文献
