一阶中立型时滞差分方程振动的充分条件

A Sufficient Condition for the Oscillation of First Order Neutral Delay Difference Equation

本文对一类一阶中立型时滞差分方程的振动给出了一个充分条件，改进了文献［１］所得的结果．

In this papar,we establish a sufficient condition for the oscillation ofcertain class of first order neutral delay difference equations. The result obtained showsthat the discrete analogue of the oscillation result in the literature[2]is true,It also improves a result in[1]。
