Investigation of the global dynamics of two exponential-form difference equations systems

In this study, we investigate the boundedness, persistence of positive solutions, local and global stability of the unique positive equilibrium point and rate of convergence of positive solutions of the following difference equations systems of exponential forms: <tex-math id="FE1"> {document}$ {equation*} Υₙ₊₁ = {Γ₁+δ₁e^{-Ψₙ₋₁}}{Θ₁+Ψₙ}, \ Ψₙ₊₁ = {Γ₂+δ₂e^{-Ωₙ₋₁}}{Θ₂+Ωₙ}, \ Ωₙ₊₁ = {Γ₃+δ₃e^{-Υₙ₋₁}}{Θ₃+Υₙ}, {equation*} document </tex-math> <tex-math id="FE2"> document {equation*} Υₙ₊₁ = {Γ₁+δ₁e^{-Ψₙ₋₁}}{Θ₁+Υₙ}, \ Ψₙ₊₁ = {Γ₂+δ₂e^{-Ωₙ₋₁}}{Θ₂+Ψₙ}, \ Ωₙ₊₁ = {Γ₃+δ₃e^{-Υₙ₋₁}}{Θ₃+Ωₙ}, {equation*} document </tex-math> for n∈ N₀ $, where the initial conditions $ Υ₋ⱼ $, $ Ψ₋ⱼ $, $ Ω₋ⱼ $, for $ j∈\{0, 1\} $ and the parameters $ Γᵢ $, $ δᵢ $, $ Θᵢ $ for $ i∈\{1, 2, 3\} $ are positive constants.
