Warmly Celebrate the Successful Seminar on Optimal Synchronization and Propagation in Higher-Order Networks at Southeast University!
On the afternoon of June 13, 2025, Southeast University hosted an academic seminar on "Optimal Synchronization and Propagation in Higher-Order Networks" at the Yongman Auditorium, Jiulonghu Campus. Co-organized by the Jiangsu Provincial Research Center for Applied Mathematics, the Jiangsu National Applied Mathematics Center (Southeast University), and the School of Mathematics at Southeast University, the seminar was supported by the Huawei-SEU Joint Innovation Laboratory on Network Swarm Intelligence and the Southeast University Education Foundation. The event also collaborated with Complex Engineering Systems.
The highlight of the seminar was a keynote lecture delivered by Prof. Guanrong Chen, Chair Professor at City University of Hong Kong, Hong Kong SAR, China, and Member of the European Academy of Sciences. Prof. Chen's lecture focused on the theory and applications of optimal synchronization and propagation in higher-order networks, drawing from network topology to explain groundbreaking research.
Keynote Speaker:
Prof. Guanrong Chen, City University of Hong Kong, Hong Kong SAR, China
Chair:
Prof. Wenwu Yu, Southeast University, Nanjing, China
Prof. Chen introduced the fundamental structure of higher-order networks and essential concepts in algebraic topology, using clear visual illustrations to show the relationships between numbers and shapes. He further elaborated on the Euler-Poincaré-Betti formula, a key theoretical breakthrough in network synchronization. His findings on fully homogeneous networks demonstrated optimal synchronizability, addressing a central question in the field of network topology.
The seminar also delved into the propagation dynamics of higher-order networks, with Prof. Chen discussing advances in the SIS and SIR models. He highlighted research methodologies, including theoretical analysis of extended second-order SIS models and Monte Carlo simulations on key parameters such as the basic reproduction number and effective reconnection rate.
In his address, Prof. Chen emphasized the paradigm-shifting impact of higher-order network theory, broadening the scope of traditional complex network theory and providing new methodologies for synchronization, propagation, and control. He encouraged young scholars to focus on cutting-edge research and strive for breakthroughs in this rapidly evolving field.
The seminar, chaired by Prof. Wenwu Yu, Editor-in-Chief of Complex Engineering Systems and a faculty member at Southeast University, was well attended both online and in person. It provided an excellent platform for academic exchange and allowed young scholars to engage with leading experts in the field.
