Abstract
In this paper we find sufficient conditions for every solution of the neutral delay difference equation
$\Delta(r_n\Delta(y_n - p_ny_n - m))+ q_nG(y_{n-k}) = 0$
to oscillate or to tend to zero or $\pm\infty$ as $n \to \infty$, where $\Delta$ is the forward difference operator given by $\Delta x_n = x_{n+1}- x_n, p_n, q_n,$ and $r_n$ are infinite sequences of real numbers with $q_n \ge 0, r_n > 0$. Different ranges of {$p_n$} are considered. This paper improves, generalizes and corrects some recent results of [1, 9, 12, 13, 14].
