Voir la notice de l'article

The Hunter–Saxton equation and the Gurevich–Zybin system are considered as two mutually non-equivalent representations of one and the same Whitham-type equation, and all their common solutions are obtained exactly.
Keywords: nonlinear PDEs; transformations; general solutions.
