摘要 借助于奇异分析的手段判断带自由参数高阶变系数耦合非线性Schrdinger方程的Painleve可积性.得到了在一定参数约束下,仅有两个子系统是Painleve可积的. By means of the singularity analysis,the Painleve integrability of the system of coupled variable coefficient higher-order nonlinear Schrdinger equations with free parameters is tested.It is shown that only two sub-systems possess the standard Painleve property under some constraints on parameters for the Painleve integrability.
