EN In this paper, we present some oscillation criteria for second order nonlinear delay difference equation with non-positive neutral term of the form ∆(an (∆zn)α)+qn f(xn–σ) = 0, n ≥ n0 > 0, where zn = xn – pn xn – τ , and α is a ratio of odd positive integers. Examples are provided to illustrate the results. The results obtained in this paper improve and complement to some of the existing results.
