建立了二阶中立型超前微分方程(1)无界解的振动准则和非振动解渐近趋向于零的充分条件.
The aim of this paper is to present sufficient conditions for all unbounded solutions of the second order advanced differential equations of the neutral type ( 1 ) to be oscillatory. Some new sufficient conditions are also derived for the convergence of nonoscillatory solutions of( 1 ) to zero.
