摘要：The boundedness character of positive solutions of the following system of difference equations: x n + 1 = A + y n p x n − 3 r $x_{n+1}=A+\frac{y^{p}_{n}}{x_{n-3}^{r}}$ , y n + 1 = A + x n p y n − 3 r $y_{n+1}=A+\frac {x^{p}_{n}}{y_{n-3}^{r}}$ , n ∈ N 0 $n\in{\mathbb{N}}_($ , when min { A , r } > 0 $\min\{A,r\}>0$ and p ≥ 0 $p\ge0$ , is studied.
