Discrete integrable system and its integrable coupling
收藏 引用
Chinese Physics B 2009年 第3期18卷 850-855页
作者: 李柱 College of Mathematics and Information Science Xinyang Normal University
This paper derives new discrete integrable system based on discrete isospectral problem. It shows that the hierarchy is completely integrable in the Liouville sense and possesses bi-Hamiltonian structure. Finally, int... 详细信息
