摘要 本文引入行波解,并应用拓展双曲函数方法,求得(2+1)维Kadomtsev-Petviashvili(KP)方程的精确解.通过应用拓展双曲函数方法,可以得到关于方程的一类有理函数形式的孤立波,行波以及三角函数周期波的精确解,并且此方法适用于求解一大类非线性偏微分进化方程. In this work,the extended hyperbolic functions method is applied to the analysis of KadomtsevPetviashvili equation.We can gain new explicit exact traveling wave solutions.The methods involved here can also be conducive to solving a large class of nonlinear evolution equations.
