Abstract

In this paper, we study a piecewise linear system of difference equations with initial condition in positive x-axis which remains an open problem. We find that there exist 5-cycles and equilibrium point. We use some direct iterative calculations and mathematical induction to prove the behaviors of solutions of the system. We separate positive x-axis into subintervals and investigate the behaviors of solutions in each of subintervals.  We also find that for such initial condition the attractors are only 5-cycles and equilibrium point. Moreover, we reveal the boundary of basins of attractions for 5-cycles and equilibrium point.               Keywords :  piecewise linear system ; periodic solution ; equilibrium point ;  difference equation
