摘要: 该文研究了时间模上的一类具有阻尼项的二阶非线性中立型变时滞Emden-Fowler型动态方程的振荡性,利用时间模上的有关理论和广义的Riccati变换及不等式技巧,建立了该方程的6个新的振荡准则,这些准则推广和改进了一些已知的结果,在时间模上也统一了相应的二阶阻尼微分方程和差分方程的振荡性质.并给出了2个实例来说明该文的主要结论.

Abstract: The oscillation for certain second-order nonlinear neutral variable delay Emden-Fowler dynamic equations with damping on time scales is discussed. By using the time scales theory and the generalized Riccati transformation and the inequality technique, we establish six new oscillation criteria for the equations. Our results extend and improve some known results, but also unify the oscillation of second-order nonlinear damped Emden-Fowler differential equations and difference equations. Two examples are given to illustrate the main results of this article.

Key words: Oscillation, Neutral dynamic equations, Time scales, Damping term, Variable delay
