摘要
给出了中立型时滞差分方程△（ｘｎ＋ｐｘｎ－ｋ）＋ｑｎｆ（ｘｎ－ｍ）＝０（Ｅ）一切非振动解趋于零（ｎ→∞）的充分条件，也证明了方程（Ｅ）一切解振动的两个新的定理．
We give sufficient conditions for all nonoscillatory solutions of the neutral delay difference equation of the form △(x n+px n-k )+q nf(x n-m )=0( E ) to converge to zero as n→∞. Two new oscillation theorems for equation (E) are also proved.
