一阶中立型线性微分系统解的振动性

Oscillation of First-order Neutral Linear Delay Differential Equations

本文给出一类一阶中立型线性微分系统解振动的充分条件 ,改进和推广了文 [1 ]的工作 .

In this paper, oscillation for a kind of first o rd er neutral linear delay differential equations is studied, and some sufficient c onditions are given, which generalize the results in the paper .
