Exact Travelling Wave Solutions for the (2+1)-Dimensional ZK-MEW Equation by Using an Improved Algebra Method

  • 摘要: 利用一种改进的统一代数方法将构造(2+1)维ZKMEW((2+1)-dimensionalZakharov-Kuznetsovmodifiedequalwidth)方程精确行波解的问题转化为求解一组非线性的代数方程组.再借助于符号计算系统Mathematica求解所得到的非线性代数方程组,最终获得了方程的多种形式的精确行波解.其中包括有理解,三角函数解,双曲函数解,双周期Jacobi椭圆函数解,双周期Weierstrass椭圆形式解等.并给出了部分解的图形.
