Abstract

This paper studied the multilayer star network synchronization with variable coupling strength. First, from the premise that the sum of the intralayer coupling strength in the network was constant, part of the coupling strength were made to vary respectively according to the rule of different functions, then it strictly derived the Supra-Laplace matrix and its eigenvalue spectrum of multilayer star network. Finally, it studied the network synchronizability on the basis of the main stability method. The simulation results show that when part of the coupling strength varies, the other coupling strength will vary in a opposite trend. Besides, the network synchronizability may be very large when the synchronous domain is bounded. The conclusion is that the trend of the synchronizability is always the same as the trend of the smaller coupling strength in the multilayer star network, and it is easier for the multilayer star network to be synchronous when the synchronous domain is bounded.
