一类具有连续变量的中立型差分方程的振动性

Oscillution of a Class of Neutral Difference Equations with Continuous Arguments

本文研究如下具有连续变量的中立型差分方程Δ(x(t) p(t)x(t-τ))+∑mi=1qi(t)x(t-σi)=0,t≥0获得了该方程的每个解振动的几个充分条件。

In this paper,we consider a class of neutral difference equations with continuous arguments.Δ(x(t)-p(t)x(t-τ)+∑mi=1qi(t)x(t-σi)=0,t≥0We obtained some sufficient conditions for the oscillatian of above equetions.
