摘要
在本文中,我们研究了具强迫项的非线性泛函微分方程(1)的振动性及渐近性,建立了一组充分性定理,结论为在满足一定条件下,当n=2时,方程(1)的所有解x(t)为振动的;当n=3时,方程(1)的所有解x(t)或者振动,或者L_kx(t)单调趋于零(k=0,1,2.)。
In this paper, the oscillatory and asymptotic behavior of nonlinear functional differential e-quations (1) with forced terms is studied and a series of sufficient theorems are established.
