摘要
研究了一类高阶亚纯函数系数线性微分方程的亚纯解的增长性,.当存在某个系数对方程的解起关键作用时,并且对方程中某个系数的零点和极点限制在某个角域内时,我们得到了方程的亚纯解增长性的精确估计.
In this paper, we study the growing properties of meromorphic solutions for higher order linear differential equations with meromorphic coefficients. The precise estimation of the properties of growth of meromorphic solutions of the equations is obtained when there exist some coefficients that play a crucial role in the equations, and the zeros and poles with some coefficients are limited in a angular domain.
