摘要

在这封信中，我们报告了修正的 Korteweg-de Vries（mKdV）方程的一种新型多孤子解。这些解同时包含三角孤子和经典孤子的 τ 函数。为了得出这些解，引入了 mKdV 方程的一种新的双线性形式。得到的解显示为生活在周期背景上的孤子，并对其进行了分析和说明。

New type of solutions for the modified Korteweg–de Vries equation

In this letter we report a new type of multi-soliton solutions for the modified Korteweg–de Vries (mKdV) equation. These solutions contain $τ$ functions of the trigonometric solitons and classical solitons simultaneously. A new bilinear form of the mKdV equation is introduced to derive these solutions. The obtained solutions display as solitons living on a periodic background, which are analyzed and illustrated.
