椭圆-椭圆聚焦Davey-Stewartson方程的周期孤子

Periodic solitons for the elliptic-elliptic focussing Davey-Stewartson equations

Mark D. Groves, Shu-Ming Sun, Erik Wahlén

摘要:

我们考虑椭圆-椭圆聚焦Davey-Stewartson方程,它有一个显式的亮线孤子解。利用动力系统论证了一类周期孤子的存在性,这类孤子在纵向空间方向上具有线孤子的轮廓,在横向空间方向上具有周期性.我们还表明,线孤子是线性不稳定的横向方向上的扰动。

英文摘要:

We consider the elliptic-elliptic, focussing Davey-Stewartson equations, which have an explicit bright line soliton solution. The existence of a family of periodic solitons, which have the profile of the line soliton in the longitudinal spatial direction and are periodic in the transverse spatial direction, is established using dynamical systems arguments. We also show that the line soliton is linearly unstable with respect to perturbations in the transverse direction.
