Temporary lag and anticipated synchronization and anti-synchronization of uncoupled time-delayed chaotic systems

Abstract

Without any control scheme and coupling terms, temporary lag and anticipated synchronization and temporary lag and anticipated anti-synchronization are newly discovered in two identical double Mackey-Glass systems with different initial conditions. When all initial conditions are positive, the lag synchronization is obtained. The negative initial values make the time history inverse and temporary lag anti-synchronization occur. The phenomena both appear intermittently. (C) 2008 Elsevier Ltd. All rights reserved.
