Global Asymptotic Behavior of a Two-dimensional System of Difference Equations Modeling Cooperation
Dedicated to Allan Peterson on the Occasion of His 60th Birthday. We investigate the global asymptotic behavior of solutions of the system of difference equations where the parameters A and B are in (0, ∞) and the initial conditions x 0 and y 0 are arbitrary nonnegative numbers. We show that the stable manifold of this system separates the positive quadrant into the basins of attraction of two types of asymptotic behavior.
