摘要: 本文用计算机考察了带外场(即变系数)非线性Shrödinger方程的孤子间碰撞机制。发现这种作变速运动的孤子碰后仍能恢复各自的形状。近年来,对孤立子的研究已深入到带外场的非线性Shrödinger方程。

Abstract: In this paper, we investigate collisions between two solitons of nonliner Shro-dinger equation with extenal field. We find that the two solitons with variable velocity can emerge again after collision.
