具有常数分离子的可积发展方程

Integrable evolution equations with constant separant

A. G. Meshkov, V. V. Sokolov

摘要:

本文给出了带常数分离子的二阶、三阶和五阶可积单场发展方程的分类结果。分类是基于必要的可积性条件,从存在的形式递归算子的可积方程。首次给出了整个无穷必要条件序列的递推公式。大多数分类声明可以在S. I. Svinilupov和V.V. Sokolov,但证据从未发表过。关于五阶方程的结果比以前得到的结果更强。

英文摘要:

The survey provides classification results for integrable one-field evolution equations of orders 2, 3 and 5 with the constant separant. The classification is based on necessary integrability conditions following from the existence of the formal recursion operator for integrable equations. Recurrent formulas for the whole infinite sequence of necessary conditions are presented for the first time. The most of the classification statements can be found in papers by S.I. Svinilupov and V.V. Sokolov but the proofs have never been published before. The result concerning the fifth order equations is stronger than obtained before.
