摘要
主要研究单位圆Δ内二阶线性微分方程f″+A(z)f′+B(z)f=F(z)解的[p,q]级,其中A(z),B(z)?0和F(z)?0是单位圆Δ内[p,q]级有限的亚纯函数,从而得出了一些复振荡结论。
In this paper,we investigate the [p,q]-order of solution of second-order linear differential equation f″+A(z)f′+B(z)f=F(z),where A(z),B(z)?0 and F(z)?0 are finite [p,q]-order meromorphic functions in the unit disc Δ,we obtain several theorems about the complex oscillation of solutions.
