Посилання:On a Whitham-Type Equation / S. Sakovich // Symmetry, Integrability and Geometry: Methods and Applications. — 2009. — Т. 5. — Бібліогр.: 21 назв. — англ.
Підтримка:The author is deeply grateful to Professor E.V. Ferapontov and Professor M.V. Pavlov for pointing out the origin of the system (3), to the referees for their useful suggestions, and to the Max-Planck-Institut f¨ur Mathematik for hospitality and support.
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.
