摘要
研究了一类具有正负系数的高阶非线性中立型时滞泛函差分方程的振动性,利用Banach空间的不动点原理,结合一些分析技巧,获得了该类方程存在非振动解的一些新的准则.
This paper is concerned with the oscillatory behavior of a class of higher order nonlinear neutral delay functional difference equation with positive and negative coefficients. By using the fixed point theorem in Banach space, and a lot of inequality techniques, some new nonoscillation criteria for the equation were obtained.
