Dual Hierarchies of a Multi-Component Camassa–Holm System
收藏 引用
Communications in Theoretical Physics 2015年 第10期64卷 372-378页
作者: 李红敏 李玉奇 陈勇 Shanghai Key Laboratory of Trustworthy Computing East China Normal University
In this paper, we derive the bi-hamiltonian structure of a multi-component Camassa–Holm system, which associates with the multi-component AKNS hierarchy and multi-component KN hierarchy via the tri-hamiltonian dualit... 详细信息

THE STRUCTURE-PRESERVING METHODS FOR THE DEGASPERIS-PROCESI EQUATION
收藏 引用
Journal of Computational Mathematics 2019年 第4期37卷 475-487页
作者: Yuze Zhang Yushun Wang Yanhong Yang Department of Applied Mathematics The Hongkong Polytechnic University China Jiangsu Key Laboratory of NSLSCS School of Mathematical Sciences Nanjing Normal University Nanjing 210023 China Department of Mathematics College of Taizhou Nanjing Normal University Taizhou 225300 China
This paper gives several structure-preserving schemes for the Degasperis-Procesi equation which has bi-hamiltonian structures consisted of both complex and non-local hamiltonian differential operators. For this sake, ... 详细信息

Blow-up criteria and periodic peakons for a two-component extension of the μ-version modified Camassa-Holm equation
收藏 引用
Communications in Theoretical Physics 2020年 第3期72卷 21-28页
作者: Zhigang Li Zhonglong Zhao Department of Mathematics China University of Mining and TechnologyBeijing 100083China Department of Mathematics North University of ChinaTaiyuanShanxi 030051China
Some two-component extensions of the modifiedμ-Camassa-Holm equation are *** show that these systems admit Lax pairs and bi-hamiltonian ***,we consider the blow-up phenomena for one of these extensions(2μmCH),and th... 详细信息
