摘要
本文给出了一类非线性泛函微分方程解的性态的若干充要条件,推广了[1]的某些结论.
Abstract According to the oscillatory properties, a classification is given for some extensively studied second-order nonlinear functional differential equations. Some sufficient conditions as well as sufficient and necessary conditions are also established for the oscillatory properties of solutions for these equations, which extend and improve some results obtained in [1].
