KP line 2-soliton


The KP equation has solitonic solutions which are exponentially localized in one spatial direction and infinitely extended in the other, so called line solitons. They generalize the KdV solitons (no y-dependence) to y-dependent solutions of KP. The video shows a 2-soliton solution, see [nlin/0512066] for more information and references.
