On the Solutions of Three-Dimensional Rational Difference Equation Systems

Abstract

In this paper, we are interested in a technique for solving some nonlinear rational systems of difference equations of third order, in three-dimensional case as a special case of the following system: $x_{n+1}=\left(y_n{z}_{n-1}/y_n\pm x_{n-2}\right),y_{n+1}=\left(z_n{x}_{n-1}/z_n\pm y_{n-2}\right),\text{\hspace{0.17em}and\hspace{0.17em}}{z}_{n+1}=\left(x_n{y}_{n-1}/x_n\pm z_{n-2}\right)$ with initial conditions $x_{-2},x_{-1},x_0,y_{-2}$ , $y_{-1},y_0,z_{-2},z_{-1},\text{\hspace{0.17em}and\hspace{0.17em}}{z}_0$ are nonzero real numbers. Moreover, we study some behavior of the systems such as the boundedness of solutions for such systems. Finally, we present some numerical examples by giving some numerical values for the initial values of each case. Some figures have been given to explain the behavior of the obtained solutions in the case of numerical examples by using the mathematical program MATLAB to confirm the obtained results.
