一阶变系数中立型泛函微分方程的振动性质

Oscillation of First Order Neutral Functional Differential Equation with Variable Coefficients

文章主要讨论形如(x(t)-P(t-l)x(t-τ))'+Q(t)G(x(t-τ))=f(t)一类变系数中立型泛函微分方程振动的性质,推广了前人的一些结果.

This paper mainly discusses oscillation of first order neutral functional differential equation( NFDE) with variable coefficients,that is,eq(1),and gets some new improvements than those before.
