摘要
研究了一类高阶非线性中立型差分方程组非振动解的存在性.利用krasnoselskii不动点定理,获得了该方程组存在非振动解的充分条件.
This paper is concerned with the existence of nonoscillatory solutions for a class of higher order nonlinear neutral system of difference equations. By using the krasnoselskii fixed theorem , we obtain a sufficient condition under which the system has a nonoscillatory solution.
