Abstract
In this paper, we obtain sufficient conditions for the oscillation of all solutions of the second order nonlinear delay difference equation Δ[a n( Δ(x n+p nx g(n))) α]+f(n,x σ(n))=0, where Δ x n = x n+1 − x n is the forward difference operator, { p n } is a sequence of nonnegative real numbers and α⩾1 is a quotient of positive odd integers. Our results extend and improve the known results in the literature. An example that dwell up the advantage of our results is included.
