BBM方程中近似相等孤子的非弹性相互作用
Inelastic interaction of nearly equal solitons for the BBM equation
摘要:
本文研究了(BBM)方程中两个速度近似相等的孤子的相互作用。这项工作是arXiv:0910.3204中由相同作者获得的结果的扩展,解决了四次(gKdV)方程的相同问题。首先,我们证明了这两个孤子的相互作用,并为所有的时间,他们分开了一个大的距离,在这种情况下的可积(KdV)方程在这个政权。其次,我们证明了碰撞不是完全弹性的,除了在可积的情况下(即在(KdV)方程的极限情况下)。
英文摘要:
This paper is concerned with the interaction of two solitons of nearly equal speeds for the (BBM) equation. This work is an extension of the results obtained in arXiv:0910.3204 by the same authors, addressing the same question for the quartic (gKdV) equation. First, we prove that the two solitons are preserved by the interaction and that for all time they are separated by a large distance, as in the case of the integrable (KdV) equation in this regime. Second, we prove that the collision is not perfectly elastic, except in the integrable case (i.e. in the limiting case of the (KdV) equation).
