带有多个滞量的二阶中立型方程振动的充要条件
Necessary and Sufficient Conditions for Oscillations of Second-order Neutral Equations With Several Delays
摘要
本文探讨了带有多个滞量的二阶中立型方程,证明该方程振动的充要条件是特征方程无实根。
This paper considered a second-order neutral equation with several days,and proved that the equation was oscillatory if and only if its characteristic equation had no real root.
