Global exponential synchronization between two different complex networks with time vary delays

This paper deals with the global exponential synchronization between two different complex networks with time vary delays. Based on the Derivation method and the Halanay inequality technique, the global exponential synchronization of two complex networks is derived between some simple conditions and some delay-independent criteria, respectively. Furthermore, the advantages of both methods were compared, simply. Finally, an illustrative example is presented to verify the effectiveness of the synchronization scheme.
