New oscillation criteria for second-order nonlinear neutral delay difference equations

Abstract

In this paper we will establish some new oscillation criteria for the second-order nonlinear neutral delay difference equation Δ(a n( Δx n+p nx n−τ) γ)+f(n,x n−σ)=0, n=0,1,2,…, where γ>0 is a quotient of odd positive integers.
