Abstract
We study a class of second-order neutral delay difference equations with positive and negative coefficients
\[\Delta(r_n(\Delta(x_n + px_{n-m}))) + p_nf(x_{n-k}) - q_ng(x_{n-l}) = 0, n = n_0, n_0 + 1,...,\]
where \(p \in R, m; k; l; n_0 \in N, p_n; q_n; r_n \in R^+; f; g \in C(R;R)\) with \(xf(x) > 0\) and \(xg(x) > 0 (x \neq 0)\). Some
sufficient conditions for the existence of a nonoscillatory solution of the studied equation expressed in terms
of
\(\sum^\infty R_np_n < 1\) and
\(\sum^\infty R_nq_n < 1\) are obtained, where\(R_n = \sum^n _{s=n_0} \frac{1 }{r_s} ; n \geq n_0\).
