A characterization of oscillation and nonoscillation of the Emden-Fowler difference equation $Δ (a_{n} {|Δ x_{n}|}^{α} s g n Δ x_{n}) + b_{n} {|x_{n + 1}|}^{β} s g n x_{n + 1} = 0$ is given, jointly with some asymptotic properties. The problem of the coexistence of all possible types of nonoscillatory solutions is also considered and a comparison with recent analogous results, stated in the half-linear case, is made.

Oscillation of nonlinear three-dimensional difference systems with delays

In this paper the three-dimensional nonlinear difference system $\begin{matrix} Δ x_{n} & = a_{n} f (y_{n - l}), \\ Δ y_{n} & = b_{n} g (z_{n - m}), \\ Δ z_{n} & = δ c_{n} h (x_{n - k}), \end{matrix}$ is investigated. Sufficient conditions under which the system is oscillatory or almost oscillatory are presented.
