一类二阶非线性脉冲时滞微分方程的振动性

Oscillation on a Class of Second Order Nonlinear Impulsive Delay Differential Equations

考虑一类二阶非线性脉冲时滞微分方程,得到了方程所有解振动的两个充分条件,推广了D■urina和Stavroulakis[Appl Math Comput,2003,140,445—453]中关于非脉冲方程的相关结果.

Consider a class of second order nonlinear impulsive delay differential equation. Two sufficient conditions for oscillation of all solutions of the equation are obtained, which extend the corresponding results of Dzurina and Stavroulakis [Appl Math Comput, 2003,140, 445-453] for equations without impulsive effects.
