一类二阶中立型时滞微分方程的振动准则

Oscillation Criteria for One Kind of Second-order Neutral Delay Differential Equations

研究了一类二阶非线性中立型时滞微分方程的振动性问题,得到了方程解振动的若干充分条件,推广和改进了已有文献中的部分结果,并对部分结果进行了验证。

This paper studies the oscillation for one kind of second-order nonlinear neutral delay dif-ferential equations.Several oscillation criteria are obtained,and some results in the documents are gener-alized and improved.Finally,one example is considered to illustrate the main results.
