摘要
扩展了Hirota法,即将Hirota法中的测试函数用新的测试函数来替代,并利用扩展了的方法来构造(2+1)维Nizhnik-Novikov-Veselov方程的周期孤子解和双周期孤子解.显然扩展的Hirota方法也可以解其他一些非线性发展方程.
Hirota method proposed recently is extended to construct more exact solutions of nonlinear evolution equa- tions. To be more precise, new text function is used instead of text function in Hirota method. By using the extended Hirota method, （2＋1 ）-dimensional Nizhnik- Novikov- Veselov equation is solved an abundance of exact periodic soliton wave so- lutions and double periodic soliton wave solutions. Obviously, the extended Hirota method can be applied to solve some oth- er nonlinear evolution equations as well.
