变系数二阶中立型微分方程非振动解的分类(英文)

A Classification Scheme for Nonoscillatory Solutions of Second Order Neutral Differential Equations with Variable Coefficients

研究一类具有正负系数的二阶中立型微分方程 ,得到了方程非振动解的渐近性 .特别 。

A class of second order neutral differential equations with positive and negative coefficients is studied and the asymptotic properties of its nonoscillatory solutions are obtained.In particular,classification schemes are derived for these solutions which are justified by existence criteria.
