Examples of Synchronization in Discrete Chaotic Systems

This paper presents an application of partial contraction analysis to the study of global synchronization in discrete chaotic systems. Explicit sufficient conditions on the coupling strength of networks of discrete oscillators are derived. Numerical examples and applications to simple systems are presented. Previous researches have shown numerically that the systems under study, when arranged in a network, exhibits rich and complex patterns that can dynamically change in response to variations in the environment. We show how this ``adaptation'' process strongly depends on the coupling characteristics of the network. Other potential applications of synchronized chaotic oscillators are discussed.
