Idea

The Korteweg de Vries equation is a differential equation, a particular nonlinear variant of a wave equation:

u t=(3u 2+u xx) x u_t = (3u^2 + u_{xx})_x

This is one of the main examples in the study of integrable systems.

It is a part of KdV hierarchy of integrable equations which in turn generalizes to KP hierarchy.
