We study synchronization in an array of coupled systems with delay and time-varying coupling and present synchronization criteria which generalize previous synchronization results. We show that the array synchronizes when the non-delay coupling term is cooperative and large enough. In particular, as in the nondelay case, the synchronization criteria is related to the second smallest eigenvalue of the matrix describing the coupling topology.
