摘要：

In this paper, we consider the delay difference equation x(n+1) - x(n) + p(n)x(n-k) = 0, n = 0, 1, 2,..., where {p(n)} is a sequence of nonnegative real numbers and k is a positive integer. Some new results for the oscillation of this equation are obtained. Our theorems improve all known results in the literature. (C) 2001 Elsevier Science Ltd. All rights reserved.
