摘要
利用Banach空间的Knaster不动点定理,证明了一类具有可变时滞的偶数阶非线性中立型差分方程最终正解的存在条件和与之相应的差分不等式最终正解的存在条件等价.
The eventually positive solution of a class of even order nonlinear neutral difference equations was concerned. By the Knaster fixed point theorem in Banach space, the necessary and sufficient condition of existence of bounded eventually positive solution for these equations was obtained.
