摘要: 讨论了一类二阶非线性微分方程.利用一般的Riccati变换和完全平方技术,得到了方程新的振动准则.结果推广并加强了已有的一些振动准则.

关键词: 二阶非线性微分方程, 阻尼项, 振动性

Abstract: The authors discuss a class of second order nonlinear differential equations. By using the generalized Riccati transformation and the integral averaging technique, new osciallation criteria are obtained for all solutions of the equations to be oscilltory. Our results generalized and extend some known oscillation criteria in the literature.

Key words: second order nonlinear differential equations, damping term, oscillation
