Abstract
In this paper we consider the existence of nonoscillatory solutions for a system of higher-order neutral differential equations with distributed coefficients and delays. We use the Banach contraction principle to obtain new sufficient conditions for the existence of nonoscillatory solutions.

Summary
1 Introduction and preliminary In this paper, we consider the system of higher-order neutral differential equations with distributed coefficients and delays b (n) r(t)x(t) + p(t, θ )x(t – θ ) dθ a d f There have been a lot of activities concerning the existence of nonoscillatory solutions for neutral differential equations with positive and negative coefficients. In , the existence of nonoscillatory solutions of the first-order linear neutral delay differential equations d dt x(t) + P(t)x(t – τ ) + Q (t)x(t – σ ) – Q (t)x(t – σ ) =
