摘要：
The boundedness and global asymptotic behavior of positive solutions of the nonlinear two-dimensional difference systems x(n) - Phi(x(n-t1), y(n-s1)), y(n) - Psi(y(n-s2), x(n-t2)), where t(1), s(1), s(2), t(2) are all positive integers, are investigated. Some sufficient conditions are established such that the positive solutions converge to the unique equilibrium. Finally, some examples are given to illustrate our results. (C) 2012 Elsevier Inc.
