超临界gKdV方程的多孤子解

Multi-soliton solutions for the supercritical gKdV equations

Vianney Combet

摘要:

对于L^2次临界和临界(gKdV)方程,Martel证明了多孤子的存在性和唯一性。回想一下,对于任何N个给定的孤子,我们称多孤子为(gKdV)的解,它的行为是这N个孤子之和随着时间的推移渐近无穷大。最近,对于L^2超临界情形,科特、马特尔和梅尔证明了至少存在一个多孤子。在本文中,建议由以前的工作有关的一个孤立子的情况下,我们首先构建了一个N-参数族的多孤子的超临界(gKdV)方程,任意给定的N个孤立子,然后证明任何多孤子属于这个家庭。换句话说,我们得到了(gKdV)的多孤子的完整分类。

英文摘要:

For the L^2 subcritical and critical (gKdV) equations, Martel proved the existence and uniqueness of multi-solitons. Recall that for any N given solitons, we call multi-soliton a solution of (gKdV) which behaves as the sum of these N solitons asymptotically as time goes to infinity. More recently, for the L^2 supercritical case, Cote, Martel and Merle proved the existence of at least one multi-soliton. In the present paper, as suggested by a previous work concerning the one soliton case, we first construct an N-parameter family of multi-solitons for the supercritical (gKdV) equation, for N arbitrarily given solitons, and then prove that any multi-soliton belongs to this family. In other words, we obtain a complete classification of multi-solitons for (gKdV).
