AI总结:

本文研究自创的高阶非线性薛定谔方程在加权Sobolev初值下的Cauchy问题,利用Lax对谱分析和Riemann-Hilbert问题结合$\bar{\partial}$-最速下降法首次推导出其长时间渐近行为。

摘要:

我们研究由我们自己推导出的一个新的高阶非线性薛定谔方程(NHNSE)在加权Sobolev初值下的Cauchy问题。通过应用$\bar{\partial}$-最速下降法,我们推导出NHNSE的长时间渐近性。具体步骤如下:首先,基于Lax对和散射矩阵的谱分析,通过求解相应的Riemann-Hilbert问题展示NHNSE的解。其次,利用Riemann-Hilbert问题的一些性质,我们得到NHNSE解的长时间渐近性。据我们所知,本文所呈现的NHNSE的性质尚未在任何学术期刊中被发现。

英文摘要:

We investigate the Cauchy problem of a new higher-order nonlinear Schrödinger equation (NHNSE) with weighted Sobolev initial data which is derived by ourselves. By applying $\bar{\partial}$-steepest descent method, we derive the long-time asymptotics of the NHNSE. Explicit steps are as follows: first of all, based on the spectral analysis of a Lax pair and scattering matrice, the solution of the NHNSE is exhibted through solving the corresponding Riemann-Hilbert problem. Secondly, by applying some properties of the Riemann-Hilbert problem, we obtain the long-time asymptotics of the solution to the NHNSE. As we know that the properties of the NHNSE presented in the paper have not been found in any scholar journals.
