摘要:
运用微分方程复振荡的理论,研究一类具有整函数系数的高阶非齐次复线性微分方程解的增长级,其中方程的系数均为整函数且非齐次项不恒为零.当方程的系数增长级满足一定的条件时,方程任一非零解具有无穷增长级.%This paper concerned with the growth of solutions of the non-homogeneous higher order linear differential equations with entire function coefficients by using complex oscillation theory of linear differ-ential equations,where the coefficients are entire functions and the non-homogeneous term unequal to zero.It is shown when the coefficients order meets certain conditions then every non-zero solution of the equation is of infinite order.

摘要:
In this paper, we investigate the distribution of the zeros of the solutions for certain higher order homogeneous linear differential equations f(k)+Ak−1f(k−1)+· · ·+A0f =0 with entire coefficients. By using the Nevanlinna’s value distribution theory, we obtain that the exponent of convergence of zeros of every transcendental solution is infinite when Ak−1 is the dominant coefficient, which extends the results of Langley and Bank.%本文研究一类整函数系数高阶齐次线性微分方程解的零点分布。利用Nevanlinna 值分布理论,得到当系数Ak−1的增长性起主要支配作用时,方程f(k)+Ak−1f(k−1)+···+A0f =0任意超越解的零点收敛指数为无穷,推广了Langley和Bank等人的结果。

摘要:
研究具有整函数函数系数的二阶非齐次线性微分方程:f" + A(z)eazf' + B(z)eP(z)f =F(z)解的复振荡,其中P(z)为非常数多项式且deg(P)=n,A(z),B(z),F(z)均为整函数且max {ρ(A),ρ(B)}<n.我们将看到方程的任一非零解具有无穷增长级.
