研究了几类具有迭代级亚纯函数系数的高阶线性微分方程亚纯解的增长性和零点分布问题,当系数a0或ad对其它系数起支配作用时,得到了方程满足一定条件的亚纯解的迭代级的一些结果,所得结果推广了前人已有结果.
The growth and the distribution of zeros of meromorphic solutions of some classes of higher order linear differential equations with meromorphic coefficients of iterated orders are investigated.Some results on the iterated order of the solutions,which satisfy some conditions are obtained,when the coefficient a 0 or a d dominates the other coefficients.Our results are extensions on previous results.
