摘要
作者对一类 N阶中立型泛函微分方程给出了新的区间振动准则。文中的结果推广和改进了由L alli等人得到的广义
New sufficient conditions are obtained for a class of n th order neutral differential equations based on a new “interval criterion” for oscillation. The work in this paper improves the generalized Kamenev's type criteria obtained by Lalli, Ruan. and Zhang, and many other known results.
