Lin–Tsien equation

From HandWiki

The Lin–Tsien equation (named after C. C. Lin and H. S. Tsien) is an integrable partial differential equation

2utx+uxuxxuyy=0.

Integrability of this equation follows from its being, modulo an appropriate linear change of dependent and independent variables, a potential form of the dispersionless KP equation. Namely, if u satisfies the Lin–Tsien equation, then v=ux satisfies, modulo the said change of variables, the dispersionless KP equation. The Lin-Tsien equation admits a (3+1)-dimensional integrable generalization, see. [1]
