Abstract: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.
Keywords:higher order nonlinear difference equations   neutral system   nonoscillatory solution
