Abstract

We investigate global dynamics of the following systems of difference equations x_n+1 = (a₁ + β₁x_n)/y_n, y_n+1 = (a₂ + y₂y_n)/(A₂ + x_n), n = 0, 1, 2, …, where the parameters a₁, β₁, a₂, y₂, and A₂ are positive numbers and initial conditions X₀ and Y₀ are arbitrary nonnegative numbers such that Y₀ > 0. We show that this system has rich dynamics which depend on the part of parametric space. We show that the basins of attractions of different locally asymptotically stable equilibrium points are separated by the global stable manifolds of either saddle points or of nonhyperbolic equilibrium points.
