二阶非线性泛函微分方程的振动性质

Oscillatory Property for Second Order Nonlinear Functional Differential Equations

研究了一类二阶非线性泛函微分方程解的振动性质.在一定条件下,应用分类讨论和分析的方法,建立了一个新的振动性定理,推广和改进了已知的结果.

This paper is concerned with oscillation property of solutions of a class of second order nonlinear functional differential equations. A new theorem is established. These results generalize the known results.
