Abstract

Abstract: Sufficient conditions have been obtained for oscillation and nonoscil-lation of solutions of a class of nonlihear differential equations with piecewise constant arguments, which generalize some results of the literature.

Key words: piecewise constant arguments, oscillation, nonoscillation

摘要： 得到含分段常数变元的非线性微分方程解的振动性和非振动性的充分条件，推广了文献中的结果。

关键词: 分段常数变元, 振动性, 非振动性
