二阶非线性中立型泛函微分方程的振动性

Oscillation for Second Order Nonlinear Neutral Functional Differential Equations

研究一类二阶非线性中立型微分方程,通过引入参数函数,结合完全平方技术,给出了该类方程解振动的判别准则,所得结果推广了已有文献的部分结果。

A class of second order nonlinear neutral differential equations is considered, and by introducing parametric function and integral square technique, oscillatory criteria of the equations are obtained. Some of the know results in the literature are extended.
