带最大值项的二阶非线性差分方程的振动性定理
Oscillation theorems of second order nonlinear difference equations with maxima
摘要
Abstract
In the paper, the oscillation of a class of second order nonlinear neutral delay difference equations with "maxima" was discussed. Using the fixed point theorem in Banach space and some necessary techniques, some sufficient conditions for the existence of eventually positive solution to the equations were obtained. Moreover, some sufficient conditions for oscillation of the equations were given.关键词
