高阶线性中立型方程的振动性──献给肖伊莘教授八十寿辰

Oscillatillations of Higher Order Linear Neutral Differential Equations

本文给出一类高阶线性中立型方程一切解振动的若干充分条件，通过减弱常用的积分发散条件，所得结果改进了文献中若干已知结果。

We obtain several sufficient conditions for the oscillation of certain classes of higher order linear neutral differental equations. Our results improve many knownresults in the literature by relaxing the conventional hypothesis for a divergent infiniteintegral.
