本文考虑了一类三阶非线性时滞微分方程。利用Riccati变换技巧,我们建立了一些新的判别准则和Kamenev型判别准则,它们保证了每一个解振荡或收敛于零.一些例子被认为是说明我们的主要结果。
In this paper, we consider a certain class of third order nonlinear delay differential equations. By m eans of th e Riccati transformation techniques we estab lish some new criteria and also Kamenev-type criteria which insure that every solution oscillates or converges to zero. Some examples are considered to illustrate our main results.
