摘要/Abstract

摘要：

研究了一类二阶广义Emden-Fowler型非线性延迟泛函微分方程的振荡性.利用广义双Riccati变换技术及一些分析技巧，在正则和非正则两种情形下获得了该方程振荡的一系列新准则，推广且改进了现有文献中的一些结果，并给出了3个实例来说明文中的主要结论.

关键词: 振荡性, 延迟, Emden-Fowler型微分方程, Riccati变换

Abstract:

We study the oscillatory behavior of a class of second-order generalized EmdenFowler-type nonlinear delay functional differential equations in this paper. By using a couple generalized Riccati transformation and some necessary analytic techniques, we establish some new oscillation criteria for the equations under both the cases canonical form and noncanonical form, which deal with some cases not covered by existing results in the literature. Three examples are given to illustrate the main results of this article.

Key words: Oscillation, Delay, Emden-Fowler-type differential equation, Riccati transformation
