Global $\mu$ -Synchronization of Linearly Coupled Unbounded Time-Varying Delayed Neural Networks With Unbounded Delayed Coupling

In this brief, we study the global synchronization of linearly coupled neural networks with delayed couplings, where the intrinsic systems are recurrently connected neural networks with unbounded time-varying delays, and the couplings include instant couplings and unbounded delayed couplings. The concept of mu-synchronization is introduced. Some sufficient conditions are derived for the global mu-synchronization for the underlined coupled systems.
