摘要
研究单位圆内高阶微分方程解的增长性,给出了单位圆内亚纯函数系数高阶微分方程解的增长性与系数增长性之间的关系,并得到了高阶微分方程不可容许解的一个充分条件。
In this paper, the properties of growth of solutions of higher order differential equations in the unit disc are investigated. It obtain relations between the growths of the solutions and the growths of the coefficients of higher order differential equations with analytic coefficients or meromorphic coefficients and obtain a sufficient condition of non - admissible solutions of higher order differential equations.
