Oscillation Criteria, Delay Neutral Difference Equations, Positive and Negative Coefficients.Resumo
This paper is concerned with a class of neutral type difference equations with positive and negative coefficients of the form\Delta(x_n − r_n x_{n−m)} + p_nx_{n−k} − q_nx_{n−l} = 0, n = 0, 1, 2, ...,
where m, k and l are nonnegative integers, and {pn} , {qn} as well as {rn} are nonnegative real sequences. Novel oscillation criteria for this equation are derived.
