Synchronization regimes in systems with multiple time-delays
  We present the first report on chaos synchronization between two unidirectionally linearly and nonlinearly coupled systems with multiple time-delays and using the Razumikhin-Lyapunov approach find the existence and stability conditions for different synchronization regimes.The approach is tested on the famous nonlinear models-Ikeda, Mackey-Glass, and Lang-Kobayashi systems.
