摘要:

应用改进的Jacobi椭圆函数法, 获得了广义Zakharov方程组新的Jacobi椭圆函数周期解. 结果表明, 在极限情形下, 某些解可以退化为相应的孤立子解和三角函数解. 该方法也可用于求解其他非线性方程组的精确行波解.

关键词: Jacobi椭圆函数法, 广义Zakharov方程组, 行波解, 孤立子解

Abstract:

We obtained a new Jacobi elliptic function periodic solutions of generalized Zakharov equations by using improved Jacobi elliptic function method. The results show that some of these solutions can be degenerated into the corresponding soliton solutions and triangular function solutions in the limit cases. This method can also be used to solve the exact travelling wave solutions of other nonlinear equations.

Key words: Jacobi elliptic function method, generalized Zakharov equations, travelling wave solution, soliton solution
