摘要
本文研究具多个滞量的二阶中立型方程,建立了所有解都振动的判别准则,并给出了一切可微解的导数振动的充分条件。
The second order neutral equation with several delay arguments is studied in this paper. Criteria for all solutions to be oscillatory are established, and sufficient con-ditions are given which ensure those derivatives of all differentiable solutions to oscillate.
