On the system of two difference equations of exponential form: x n+1 =a+bx n-1 e -y n , y n+1 =c+dy n-1 e -x n . (English) Zbl 1235.39006

Summary: Our goal is to study the boundedness, the persistence and the asymptotic behavior of the positive solutions of the system of two difference equations of exponential form

x n+1 =a+bx n-1 e -y n ,y n+1 =c+dy n-1 e -x n ,

where a,b,c,d are positive constants, and the initial values x -1 ,x 0 ,y -1 ,y 0 are positive real values.
