摘要

本文给出一类具有多个次线性中立项的二阶微分方程一切解振动的若干新的充分条件。我们的结果不仅推广了经典的振动定理,而且改进和概括了最近文献中的振动结果,为说明所得结果的重要性，我们也给出了相应的例子。

Abstract

Some news sufficient conditions for oscillation of all solutions of a class of second order differential equations with several sub-linear neutral terms are given. Our results not only extend several classical oscillation theorems but also improve and generalize those reported in the literature, recently. Examples are included to illustrate the importance of the results obtained.
