Abstract

In this paper we present the well-defined solution of the following system of higher-order rational difference equations:

$$\begin{aligned} x^{(j)}_{n+1}=\frac{x^{(j+1)\pmod {p}}_{n-k}}{a+bx^{(j+1)\pmod {p}}_{n-k}},\quad n, p, k\in \mathbb {N}_0 , j=\overline{1,p}, \end{aligned}$$

where the parameters ab are nonzero real numbers and the initial values \(x^{(j)}_{-k}\), \(x^{(j)}_{-k+1}\),\(\ldots \), \(x^{(j)}_{-1}\) and \(x^{(j)}_0,\) \(j=\overline{1,p}\), do not equal \(-\frac{a}{b}\). Some theoretical explanations related to the representation for the general solution are also given.
