Abstract

In this paper, we study the persistence, boundedness, convergence, invariance and
global asymptotic behavior of the positive solutions of the second-order diference
system
xn+1 = α1 + ae−xn−1 + byne−yn−1 ,
yn+1 = α2 + ce−yn−1 + dxne−xn−1 n = 0, 1, 2, ... where α1, α2, a, b, c, d are
positive real numbers and the initial conditions x−1, x0, y−1, y0 are arbitrary nonnegative
numbers.
