INVARIANT SUBSPACES AND generalized FUNCTIONAL SEPARABLE SOLUTIONS TO THE TWO-COMPONENT b-FAMILY SYSTEM
收藏 引用
Acta Mathematica Scientia 2016年 第3期36卷 753-764页
作者: 闫璐 时振华 王昊 康静 Xingzhi College Xi'an University of Finance and Economics School of Mathematics Northwest University Center for Nonlinear Studies and School of Mathematics Northwest University
Invariant subspace method is exploited to obtain exact solutions of the two- component b-family system. It is shown that the two-component b-family system admits the generalized functional separable solutions. Further... 详细信息

Chinese Physics B 2006年 第12期15卷 2765-2776页
作者: 张顺利 楼森岳 屈长征 Institute of Modern Physics Northwest University Xi'an 710069 China Department of Mathematics Northwest University Xi' an 710069 China Center of Nonlinear Science Ningbo University Ningbo 315211 China
This paper studies variable separation of the evolution equations via the generalized conditional symmetry. To illustrate, we classify the extended nonlinear wave equation utt = A(u, ux)uxx+B(u, ux, ut) which adm... 详细信息
