Backlund Transformation and Exact Solutions for Whitham-Broer-Kaup Equations in Shallow Water

Institute of Mathematics, Dalian University of Technology, Dalian 116024, P. R. China

摘要: 用一种新的方法并借助Mathematica,求出了Whitham-Broer-Kaup(简记WBK)方程的一种Backlund变换,并建立了WBK方程与热传导方程及Burgers方程的联系.利用这种关系得到了WBK方程的三组精确解,其中一组为孤波解.

Abstract: By using a new method and Mathematica,the Backlund transformations for Whitham-Broer-Kaup equations(WBK)are derived.The connections between WBK equation,heat equation and Burgers equation are found,which are used to obtain three families of solutions for WBK equations, one of which is the family of solitary wave solutions.
