多时滞非线性差分方程振动解的渐近性

The asymptotic behavior of nonlinear difference equations with several delays

给出了多时滞非线性差分方程 Δxn+anxn+f n,∑0s=- kqsxn+s =0 ,(n≥ 0 )所有振动解 xn趋于0的一族充分条件。

the asymptotic behavior of the difference equations with several delays Δx n+a nx n+fn,∑0s=-kq sx n+s =0 is considered,some sufficient conditions that guarantee all oscillalting solutions to tending to zero are established. Some known results are generated and improved.
