摘要
研究了时空分数阶复Ginzburg⁃Landau方程.首先通过分数阶复变换将时空分数阶复Ginzburg⁃Landau方程转化为一个常微分方程.然后将常微分方程化为初等积分形式.最后用多项式完全判别系统法求得一系列精确解,其中包含有孤立波解、有理函数解、三角函数周期解、Jacobi椭圆函数双周期解.
The space⁃time fractional complex Ginzburg⁃Landau equation was studied.Firstly,the space⁃time fractional complex Ginzburg⁃Landau equation was transformed into the ordinary differential equation through the fractional complex transform.Secondly,the ordinary differential equation was reduced to an elementary in⁃tegral form.Finally,a series of exact solutions including solitary wave solutions,rational function type solu⁃tions,triangle function type periodic solutions,and Jacobian elliptic function doubly⁃periodic solutions,were constructed with the complete discrimination system for polynomial method.
