Dynamical behavior of a system of three-dimensional nonlinear difference equations

In this paper, we study the boundedness, persistence, and periodicity of the positive solutions and the global asymptotic stability of the positive equilibrium points of the system of difference equations xₙ₊₁=A+xₙ₋₁zₙ, yₙ₊₁=A+ yₙ₋₁z ₙ, zₙ₊₁=A+zₙ₋₁yₙ, n=0,1,… , where A∈ ( 0,∞ ) and the initial conditions xᵢ , yᵢ , zᵢ∈ ( 0,∞ ) , $i=-1,0$ .
