修正的KP方程中扭结孤子的共振结构

The resonant structure of Kink-Solitons in the Modified KP Equation

Jen-Hsu Chang

摘要:

利用$τ$ -函数的Wronskian表示,可以研究修正KP方程的扭结孤子和线孤子的共振结构。研究发现,在完全非负的格拉斯曼$Gr(N,M)_{ \geq 0}$中,给定一个不可约Schubert胞腔,孤子图的共振结构是由两个Le图的两个相应孤子图的叠加得到的.给出了几个例子。

英文摘要:

Using the Wronskian representation of $τ$-function, one can investigate the resonant structure of kink-soliton and line-soliton of the modified KP equation. It is found that the resonant structure of the the soliton graph is obtained by superimposition of the two corresponding soliton graphs of the two Le-Diagrams given an irreducible Schubert cell in a totally non-negative Grassmannian $Gr(N,M)_{ \geq 0}$. Several examples are given.
