Sk. Liu et al., Expansion method about the Jacobi elliptic function and its applications to nonlinear wave equations, ACT PHY C E, 50(11), 2001, pp. 2068-2073
A Jacobi elliptic function expansion method is proposed to construct the ex
act periodic solutions of nonlinear wave equations. This new method contain
s the hyperbolic tangent expansion method, and the periodic solutions obtai
ned by this method, include the shock wave solutions and the solitary wave
solutions.
