摘 要: 主要研究了一类迭代级亚纯函数系数高阶齐次线性微分方程解的增长性问题.当系数A0对方程解的性质起主要支配作用时,得到了方程解的迭代级的精确估计,推广了已有的结果. In this paper, we investigate the growth of solutions of a class of higher order homogeneous linear differential equation with meromorphic coeiticients of iterated order. For most of meromorphic solutions, we obtain precise estimate of their iterated order. We also improve the results obtained before.
