研究具有迭代级整函数系数的高阶线性微分方程解的增长性和零点问题.当存在某一系数起主导作用时,得到方程解的迭代级和迭代零点收敛指数的估计,推广了已有的结论.
The growth and zeros of solutions of higher order linear differential equations with entire coefficients of finite iterated order are studied. Some estimations on the iterated order and the iterated convergence exponent of zero sequence are obtained,when there exists one dominant coefficients. The obtained results are extensions of some previous results.
