Аннотация:In the paper, the discrete Emden-Fowler equation $$\Delta62 u(k) \pm k^\alpha u^m (k) = 0$$ is considered, where $k \ge k_0$, $k$ is an independent variable, $k_0$ is a fixed integer,$u: \{k_0,k_0 + 1,...\} \to \mathbb{R}$, $\Delta u(k)$ is the first difference of $u(k)$, $Delta^2u(k)$ is the second difference of $u(k)$, $m$ and $\alpha$ are real numbers. A result on asymptotic behaviour of solutions when $k \to \infty$ is proved and admissible values $m$ and $\alpha$ satisfying assumptions of this result are considered in an $(m,\alpha)$-plane.
