一类三阶中立型半线性时滞微分方程振动准则

Oscillate Criteria of Third Order Semi-Linear Neutral Differential Equations with Delay Argument

本文研究一类三阶中立型半线性时滞微分方程振动性质,利用广义Riccati变换和经典不等式技巧,参考最近论文结果,建立了一个新的振动性准则,并给出证明和例子。

We study the oscillatory of third order semi-linear neutral differential equations with delay argument. Using a generalized Riccati substitution and inequation technique, and consulting some results in recent literature, a new oscillation criterion is established and proved, also a number of examples are given to prove their efficiency..
