摘要
利用亚纯函数的Nevanlinna值分布理论和方法,研究了一定条件下复域内高阶微分方程组亚纯允许解的估值问题,对一类特殊的高阶复微分方程组允许解的估计做了改进.
Applying the Nevanlinna value distribution theory and methods of meromorphic functions,this paper studies the estimation of meromorphic admissible solutions to systems of complex higher-order differential equations under a certain condition. The estimation of the admissible solutions to some special systems of higher-order complex differential equations is improved.
