摘要
运用改进的tanh函数法,利用一种新的Riccati方程得到三维空间中Klein-Gordon-Zakharov方程的精确解.包括sech型的孤子解、tanh型的孤子解、三角函数的周期解、有理解、Jacoobi椭圆函数解,共5种类型的13组解.
In this paper, by using a new class of Riccati equations and the extended tanh-fuction method, exact solutions of the Klein-Gordon-Zakharov equations in three space dimensions are constructed. The solutions not only include sech-solition solutions, tanh-soliton solutions, rational solutions, but also include triangle function periodic solutions and Jacobi ellipse ruction solutions. Total- ly there are thirteen solutions which are of five different type of function.
