This paper investigates epidemic control behavioral synchronization for a class of complex networks resulting from spread of epidemic diseases via pinning feedback control strategy. Based on the quenched mean field theory, epidemic control synchronization models with inhibition of contact behavior is constructed, combining with the epidemic transmission system and the complex dynamical network carrying extra controllers. By the properties of convex functions and Gerschgorin theorem, the epidemic threshold of the model is obtained, and the global stability of disease-free equilibrium is analyzed. For individual's infected situation, when epidemic spreads, two types of feedback control strategies depended on the diseases' information are designed: the one only adds controllers to infected individuals, the other adds controllers both to infected and susceptible ones. And by using Lyapunov stability theory, under designed controllers, some criteria that guarantee epidemic control synchronization system achieving behavior synchronization are also derived. Several numerical simulations are performed to show the effectiveness of our theoretical results. As far as we know, this is the first work to address the controlling behavioral synchronization induced by epidemic spreading under the pinning feedback mechanism. It is hopeful that we may have more deeper insight into the essence between disease's spreading and collective behavior controlling in complex dynamical networks., Comment: 22 pages, 8 figures

In real world, there is a significant relation between human behaviors and epidemic spread. Especially, the reactions among individuals in different communities to epidemics may be different, which lead to cluster synchronization of human behaviors. So, a mathematical model that embeds community structures, behavioral evolution and epidemic transmission is constructed to study the interaction between cluster synchronization and epidemic spread. The epidemic threshold of the model is obtained by using Gersgorin Lemma and dynamical system theory. By applying the Lyapunov stability method, the stability analysis of cluster synchronization and spreading dynamics are presented. Then, some numerical simulations are performed to illustrate and complement our theoretical results. As far as we know, this work is the first one to address the interplay between cluster synchronization and epidemic transmission in community networks, so it may deepen the understanding of the impact of cluster behaviors on infectious disease dynamics., Comment: 22 pages, 8 figures

Real epidemic spreading networks often composed of several kinds of networks interconnected with each other, and the interrelated networks have the different topologies and epidemic dynamics. Moreover, most human diseases are derived from animals, and the zoonotic infections always spread on interconnected networks. In this paper, we consider the epidemic spreading on one-way circular-coupled network consist of three interconnected subnetworks. Here, two one-way three-layer circular interactive networks are established by introducing the heterogeneous mean-field approach method, then we get the basic reproduction numbers and prove the global stability of the disease-free equilibrium and endemic equilibrium of the models. Through mathematical analysis and numerical simulations, it is found that the basic reproduction numbers $R_0$ of the two models are dependent on the infection rates, infection periods, average degrees and degree ratios. In the first model, the network structures of the inner contact patterns have a bigger impact on $R_0$ than that of the cross contact patterns. Under the same contact pattern, the internal infection rates have greater influence on $R_0$ than the cross-infection rates. In the second model, the disease prevails in a heterogeneous network has a greater impact on $R_0$ than the disease from a homogeneous network, and the infections among the three subnetworks all play a important role in the propagation process. Numerical examples verify and expand these theoretical results very well.
