摘要
研究了一类带有最大值项的高阶非线性中立型时滞差分方程正解的存在性,利用Banach空间的不动点原理和一些分析技巧,得到了这类方程存在最终正解的几个充分条件,同时给出例子验证其有效性.
In this paper, the existence of positive solution for a class of the higher order nonlinear neutral delay difference equations with ＂maxima＂ is studied. By using the fixed point theorem in Banach space and some necessary techniques, some sufficient conditions for the existence of eventually positive solution of the equations are obtained. The examples are presented to illustrate the effects of our theorems.
