On some systems of difference equations

Applied Mathematics and Computation, 2011
The authors consider the following three systems of nonlinear difference equations \[ u_{n+1}=\frac{v_n}{1+v_n},\quad v_{n+1}=\frac {u_n}{1+u_n}, \] \[ u_{n+1}=\frac{v_n}{1+u_n},\quad v_{n+1}=\frac {u_n}{1+v_n}, \] and \[ u_{n+1}=\frac{u_n}{1+v_n},\quad v_{n+1}=\frac {v_n}{1+u_n}, \] where \(n\in {\mathbb N}_0\) and the initial values \(u_0\) and \(v_0\
