摘要
研究了一类三阶常系数的中立型时滞微分方程的振动准则,得到了在不同条件下的振动准则.给出了这类中立型时滞微分方程振动的必要和充分条件.
Studying the oscillation of a class of third order neutral delay differential equations with constant coefficients and getting the criterion of oscillation under different conditions. Besides, the necessary and sufficient conditions are given. And some examples are considered to illustrate the results.
