时间尺度上三阶非线性中立型动力方程的振动准则

源于电子工程、机械工程、生态工程和航天工程等领域的许多问题均可用时间尺度上的动力方程来描述，因此，研究这类方程有着重要的理论价值和实际意义。本文利用广义Riccati变换，积分平均和比较原理，研究了一类时间尺度上三阶非线性中立型时滞动力方程的振动性和渐近性，给出了这类方程新的Kamenev型振动准则和Philos型振动准则。本文成果推广了已知文献的多个相应结果并给出了例证。

Oscillation Criteria for Third-order Nonlinear Neutral Dynamic Equations on Time Scales

Many practical problems, such as those from electronic engineering, mechanical engineering, ecological engineering, aerospace engineering and so on, need to be described by dynamic equations on time scales, so it is important in theory and practical significance to study these equations. In this paper, the oscillation and asymptotic behavior of third-order nonlinear neutral delay dynamic equations on time scales are studied by using generalized Riccati transformation technique, inte-gral averaging methods and comparison theorems. The main purpose of this paper is to establish some new oscillation criteria for such dynamic equations. The new Kamenev criteria and Philos criteria are given, and an example is considered to illustrate our main results.
