We show that the following two-dimensional system of difference equations:where (a n ) n∈N 0 , (b n ) n∈N 0 , (c n ) n∈N 0 , and (d n ) n∈N 0 are periodic sequences, is solvable, considerably extending some results in the literature. In the case when all these four sequences are periodic with period 2 or with period 3, we present closed-form formulas for the general solutions to the corresponding systems of difference equations. Some comments regarding theoretical and practical solvability of the system, connected to the value of the period of the sequences, aregiven.

“…For more studied, see previous works. [9][10][11][12][13][14][15][16][17][18][19][20][21] There are many forms and types of rational difference equations which can be studied in different cases; for example, Stevi ć et al 22 solved the next rational difference equations w n+1 = w n−h w n−i 𝛼 w n−𝑗 + 𝛽 w n−k .…”

In this paper, we construct the solutions expressions for a system of three‐dimensional nonlinear difference equations Rn+1=a1Tn−1Sn−1Rn−1+Sn−1+Tn−1,Sn+1=a2Tn−1Rn−1Rn−1+Sn−1+Tn−1,Tn+1=a3Rn−1Sn−1Rn−1+Sn−1+Tn−1. In addition, we prove some properties of the proposed system such as boundedness and periodicity of the positive solutions and the global asymptotic stability of the equilibrium points. Finally, we present some numerical examples in order to illustrate the theoretical results.

General k-Dimensional Solvable Systems of Difference Equations

Abstract: Abstract:The solvability of a k-dimensional system of difference equations of interest, which extends several recently studied ones, is investigated. A general sufficient condition for the solvability of the system is given, considerably extending some recent results in the literature.
