✦ Synopsis

In this paper, we consider the following higher-order neutral delay difference equations with positive and negative coefficients:

where c E W, m 2 1, k 2 1, r,Z 2 0 are integers, and {pn}~zn=n, and {qn}r&, are sequences of nonnegative real numbers. We obtain the global results (with respect to c) which are some sufficient conditions for the existences of nonoscillatory solutions.
