摘要: 研究了一类具有非线性中立项的二阶变时滞微分方程的振动性.采用广义的Riccati变换及多种不等式技巧,获得了该类方程的2个新的Kamenev型振动准则,这些准则能用于其他已知结果不适用的情形,推广并改进了相关文献的结果.
关键词: 振动性变时滞非线性中立项    
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.
Key words: oscillation    variable delay    nonlinear neutral
