Integrable Semi-Discretization for a Modified Camassa-Holm Equation with Cubic Nonlinearity
Bao-Feng Feng, Heng-Chun Hu, Han-Han Sheng +2
In the present paper, an integrable semi-discretization of the modified Camassa-Holm (mCH) equation with cubic nonlinearity is presented. The key points of the construction are bas…
Coupled KdV equations derived from atmospherical dynamics
S. Y. Lou, Bin Tong, Heng-chun Hu +1
Some types of coupled Korteweg de-Vries (KdV) equations are derived from an atmospheric dynamical system. In the derivation procedure, an unreasonable -average trick (which is u…
Darboux Transformation and Variable Separation Approach: the Nizhnik-Novikov-Veselov equation
Heng-chun Hu, Sen-yue Lou, Qing-ping Liu
Darboux transformation is developed to systematically find variable separation solutions for the Nizhnik-Novikov-Veselov equation. Starting from a seed solution with some arbitrary…
New Darboux Transformation for Hirota-Satsuma coupled KdV System
Heng Chun Hu, Q. P. Liu
A new Darboux transformation is presented for the Hirota-Satsuma coupled KdV system. It is shown that this Darboux transformation can be constructed by means of two methods: Painle…
Decouple a coupled KdV system of Nutku and Oguz
Heng Chun Hu, Q. P. Liu
A coupled KdV system with a free parameter proposed by Nutku and Oguz is considered. It is shown that the system passes the WTC's Painlevé test for arbitrary value of the parameter…
