在本文采用经典李群方法获得准确的立方Klein—Gordon方程的行波解,采用雅可比椭:圆函数得到了一些新的解,我们也得到了立方Klein—Gordon方程的守恒律.
In this paper, the classical Lie group method is employed to obtain exact traveling wave solutions of the cubic Klein-Gordon equation (cKG). Some new solutions of the solutions be derived by applying Jacobi Elliptic function equation. We also give the conservation laws of the cKG equation.
