一类二阶微分方程新的Kamenev型振动准则
Kamenev-type oscillation criteria for certain second-order differential equations
摘要
Abstract
We study the oscillatory behavior of a class of second-order variable delay differential equations with a nonlinear neutral term in this article.By using the generalized Riccati transformation and inequality technique, two new Kamenev-type oscillation criteria are presented that can be used in cases when the known results fail to apply.Our results extend and improve some related results reported in the literature.关键词
