(2+1)维破裂孤子方程组的周期孤波解

Periodic Wave Solutions for Nizhnik Equations

把(2+1)维破裂孤子方程组写成双线性型,运用Hirota法,将Hirota法中的测试函数用新的测试函数来替代,求得(2+1)维破裂孤子方程组新的周期孤波解和不曾看见过的解析解.该方法适用于部分非线性方程.

（2 ＋ 1 ）-dimension breaking soliton equations are translated to bilinear form. New text function is used instead of text function in Hirota method. By using the extended Himta method, （2 ＋ 1 ）- dimension breaking soliton equations are solved an abundance of periodic wave solutions and exact solutions that we can＇t see before. Obviously, the extended Hirota method can be applied to solve other type of nonlinear evolution equations as well.
