Synchronization of drive-response singular Boolean networks

Network synchronization, explicating typical collective behaviors of coupled systems, plays a crucial role in social production and life. This paper addresses the synchronization problem of drive-response singular Boolean networks (SBNs). The solvability of drive- response SBNs is investigated based on the matrix representation. In view of the existence and uniqueness of the solutions to drive-response SBNs, three types of concepts, synchronization, strong synchronization and weak synchronization, are put forward for the first time. By two new systems, a restricted BN and a switched restricted BN, which are constructed from the considered systems, several synchronization conditions are provided to deal with the circumstances of unique solutions and multiple solutions, respectively. Besides, the synchronous ratio is defined to characterize the synchronization capability of drive-response SBNs for the case of multiple solutions. Finally, several examples are given to illustrate the effectiveness of the obtained results. (C)& nbsp;2021 Elsevier Ltd. All rights reserved.
