二阶中立型超前微分方程的振动性和渐近性

Oscillation of Solutions of Second Order Neutral Differential Equations with Advanced Argument

    摘要
  • 摘要: 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.

     

    Abstract: 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.
