摘要
以微积分为基本工具讨论一类具正负系数中立型时滞差分方程的振动性 ,得到了几个新的保证这个方程的所有解振动的充分条件 ,所得结果改进了已有文献中的相应结论 ,并给出了其应用。
In this paper, we obtain some new sufficient conditions for the oscillatory behavior of the neutral delay difference equation with positive and negative Coefficients on the basic of calculus. The results improve some known results of neutral delay difference equation. And some applications of the main results are given.
