二阶中立型微分方程的振动性和渐近性

Oscillation and Asymptotic Behavior of Second Order Neutral Differential Equations

研究了一类具有变系数二阶中立型微分方程的非振动性和振动性．讨论了方程的非振动解的渐近性．给出了方程的所有解振动的充分条件．所得结论推广了已知的一些结果．

The purpose of this investigation is to study nonoscillations and oscillations of a class of second order neutral differential equations with variable coefficients. The asymptotic behavior of nonoscillatory solutions of equations was discussed and the sumcient conditions for all solutions of such equations to oscillate was given. The conclusions extend some known results.
