具可变时滞的二阶非线性中立型泛函微分方程的振动性
Oscillation of certain second-order nonlinear neutral functional differential equations with variable delay
摘要
Abstract
We study the oscillatory behavior of a class of second‐order nonlinear neutral functional differential equa‐tions with variable delay .By using the generalized Riccati transformation and the inequality technique ,we establish two new oscillation criteria for the oscillation of the equations .The examples are provided to illustrate that our re‐sult gives a sharper estimate for the oscillation of the equations .关键词
