On the system of rational difference equations xn = A+yn−1/xn−pyn−q, yn = A+xn−1/xn−ryn−s

In this paper, we study the behavior of positive solutions of the system of difference equations xn = A + yn−1 xn−pyn−q , yn = A+ xn−1 xn−r yn−s , n= 1, 2, . . . , where p 2, q 2, r 2, s 2, A is a positive constant, and x1−max{p,r}, x2−max{p,r}, . . . , x0, y1−max{q,s}, y2−max{q,s}, . . . , y0 are positive real numbers.  2004 Elsevier Inc.
