摘要

摘要我们利用全非负格拉斯曼构造了复 KP 方程的奇偶时对称孤子。我们得到完全非负正交格拉斯曼中的每个元素都对应于一个奇偶时对称孤子解。

Parity–time symmetric solitons of the complex KP equation

Abstract

We construct the parity–time symmetric solitons of the complex KP equation using the totally nonnegative Grassmannian. We obtain that every element in the totally nonnegative orthogonal Grassmannian corresponds to a parity–time symmetric soliton solution.
