In this paper, we consider the delay diff~ence equation Zn+l-Xn+Pnzn-k=O, n=0,1,2,..., where {p,) 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. (~) 2
