一类时滞微分方程的振动性

On Oscillations of a Nonlinear Neutral Differece-Differential Equations

本文讨论了一类时滞微分方程d/dt×f(t,x(t),x(t-r))+p(l)x(t-x)-q(t)x(t-σ)=0的振动性,推广了文[8]的部分结果。

In this paper,we discuss the oscillations of a nonlinear neutral differece-differential equations d/(dt)f(t,x(t),x(t - r)) + p(t)x(t -τ) - q(t)x(t - σ)=0 .
