Since the largest Lyapunov exponent is nonpositive, trajectories in two such identical but distinct systems show the property of {\it phase}--synchronization. Our results are illustrated in the model SQUID and Rössler oscillator systems.To be appeared as a Book Chapter dedicated to Prof. M Lakshmanan on the occasion of his sixtieth birthdayChaotic Dynamicstext
