高阶约束流的可积Rosochatius变形和具有自洽源的孤子族

Integrable Rosochatius deformations of higher-order constrained flows and the soliton hierarchy with self-consistent sources

Yuqin Yao, Yunbo Zeng

摘要:

我们提出了一个系统的方法来推广可积Rosochatius变形有限维可积Hamilton系统的可积Rosochatius变形的无限维可积方程。给出了包括广义可积H $\acute{e}$非Heiles系统在内的若干孤子族的无穷多个可积Rosochatius变形高阶约束流,以及自洽源KdV族、自洽源AKNS族和自洽源mKdV族的可积Rosochatius变形及其Lax表示.

英文摘要:

We propose a systematic method to generalize the integrable Rosochatius deformations for finite dimensional integrable Hamiltonian systems to integrable Rosochatius deformations for infinite dimensional integrable equations. Infinite number of the integrable Rosochatius deformed higher-order constrained flows of some soliton hierarchies, which includes the generalized integrable H$\acute{e}$non-Heiles system, and the integrable Rosochatius deformations of the KdV hierarchy with self-consistent sources, of the AKNS hierarchy with self-consistent sources and of the mKdV hierarchy with self-consistent sources as well as their Lax representations are presented.
