摘要
研究一类二阶非线性泛函微分方程.(r(t)x′(t))′+a(t)f(x(t),x(t-τ(t))=0解的振动性,提出一组相当规范的振动性条件,进而得到方程一切解振动的基本结果和若干推论.
The oscillation for a class of second order noninear functional differential equations is studied,and three normal oscillation conditions are given.Futher,the fundamental results and several corollaries are obtained.
