Oscillation Properties of Solutions for Damped Delay-Differential Equations

本文给出了一类具有阻尼项的非线性时滞微分方程的一切解均为振动的若干充分条件，所得结果推广了文献［３］和［５］的工作。

Abstract In the present paper some sufficient conditions have been found for which all solutions of the nonlinear delay-differential equations with damping are oscillatory.Our results generalize the works in papers [3],[5].
