改进的Korteweg-de Vries方程多呼吸子唯一性

Improved uniqueness of multi-breathers of the modified Korteweg-de Vries equation

Raphaël Côte, Alexander Semenov

摘要:

我们考虑(mKdV)的多呼吸子。以前,一个光滑的多呼吸器被构造,并证明是唯一的在两种情况下:第一,如果类的超多项式收敛到的轮廓,第二,假设所有的呼吸器的速度都是积极的(没有收敛速率)。这篇短文的目的是改进第二个结果:我们证明了当至多有一个速度为负或为零时,唯一性仍然成立。

英文摘要:

We consider multi-breathers of (mKdV). Previously, a smooth multi-breather was constructed, and proved to be unique in two cases: first, if the class of super-polynomial convergence to the profile, and second, under the assumption that all speeds of the breathers involved are positive (without rate of convergence). The goal of this short note is to improve the second result: we show that uniqueness still holds if at most one velocity is negative or zero.
