Global asymptotic behavior of a two-dimensional difference equation modelling competition. (English) Zbl 1019.39006

Nonlinear Anal., Theory Methods Appl., Ser. A, Theory Methods 52, No. 7, 1765-1776 (2003).
Consider the system of difference equations \[ x_{n+1}=\frac{x_n}{a+cy_n},\quad y_{n+1}=\frac{y_n}{b+dx_n}\quad n=0,1,\dots \quad (x_0\geq 0,\;y_0\geq 0)\tag{1} \] where \(a\) and \(b\) are in \((0,1),c\) and \(d\) are positive numbers. The global asymptotic behavior of solutions of (1) is investigated. The authors show that the stable manifold of (1) separates the positive quadrant into basins of attraction of two types of asymptotic behavior. An explicit equation for the stable manifold is obtained in the case where \(a=b\).
