二阶非线性摄动微分不等式的振动性质

Oscillatory Property for Second Order Differential Inequality With Perturbation

研究了一类二阶非线性摄动微分不等式解的振动性质.在一定条件下,应用分类讨论和分析的方法,建立了两个新的振动性定理,推广和改进了已知的结果.

This paper is concerned with oscillation proverty of solutions of a class of second order nonlinear differential inequality with perturbation. Two new theorems are established. These results generalize the known results.
