摘要 研究时间测度链上的一类具有非线性中立项的二阶非线性变时滞动力方程的振动性.利用时间测度链上的理论和一些分析技巧,通过引入参数函数和Riccati变换,得到该方程振动的几个充分条件.给出了一些例子以说明主要结论. Oscillation of second-order nonlinear variable delay dynamic equations with nonlinear neutral term on time scales is discussed.By using the time scale theory and some necessary analytic techniques and by introducing parameter functions and the generalized Riccati transformation,some sufficient conditions for the oscillation of the equations are obtained.Some examples are given to illustrate our main conclusions.
