In this paper we obtain some new oscillation criteria for the neutral difference equationΔ(a_n(Δ(x_n - p_nx_(n - k))))+qn f (x_(n - l)) = 0where 0 ≤ p_n ≤ p 1, q_n 0 and l and k are positive integers. Examples are presented to illustrate the main results. The results obtained in this paper improve and complement to the existing results.
