摘要
在本文中,我们研究了一类较广泛的二阶非线性泛函微分方程的振动性质。文中指出,在一定条件下,方程的非振动解仅有两类,而且给出了每一类非振动解存在的必要条件,同时也建立了方程振动的若干充分判据。
In this paper,we study the oscillatory behavior for second order nonlinear functionaldifferential equation. On some conditions,we obtain the nonoscillatory solutions only have twokind, and necessary conditions for existence of each kind nonoscillatory solutions.At the sametime, we establish some sufficient conditions for oscillatory solutions.
