Oscillation of certain third-order variable delay damped dynamic equations on time scales

讨论了时间尺度上一类具阻尼项和非线性中立项的三阶非线性变时滞动态方程的振荡性,利用广义的Riccati变换和不等式技巧,获得了该方程的一些新的振荡准则,推广并改进了现有文献中的一些结果,本文的这些结果对于作为其特例的相应三阶差分方程和微分方程来说也是新的,最后通过例子来说明了文章中的这些结果的重要性.

The oscillation for certain third-order nonlinear variable delay dynamic equa- tions with damping term and nonlinear neutral term on time scales is discussed in this article. By using the generalized Riccati transformation and inequality technique, some new oscillation criteria for the equations are established. Our results extend and improve some known results in the literature. Many of the results in this paper are new for the corresponding third-order difference equations and differential equations being as special cases. Some examples are given to illustrate the importance of our results.
