On Leadership Emergence in Opinion Dynamics on Social Networks
Martina Alutto, Lorenzo Zino, Karl H. Johansson +1
Leadership in social groups emerges dynamically through interaction and opinion exchange. Empirical evidence indicates that individuals expressing strong opinions tend to gain infl…
Hyperedge approximation for stochastic processes on higher-order networks
Anzhi Sheng, Alex McAvoy, Ye Tian +3
Graphs are a standard framework for describing dynamical processes shaped by pairwise interactions among agents. But many systems involve interactions in groups of three or more ag…
Topology Identification of Dynamical Signed Graphs
Pelin Sekercioglu, Nana Wang, Angela Fontan +1
We propose an adaptive control protocol for identifying the topology of dynamical networks interconnected over undirected graphs with cooperative and antagonistic interactions. The…
Dynamical models for distributed social power perception in Friedkin-Johnsen influence networks
Ye Tian, Angela Fontan, Yu Kawano +3
Social power quantifies the ability of individuals to influence others and plays a central role in social influence networks. Yet, computing social power typically requires global…
Edge-based Synchronization over Signed Digraphs with Multiple Leaders
Pelin Sekercioglu, Angela Fontan, Dimos V. Dimarogonas
This work addresses the edge-based synchronization problem in first-order multi-agent systems containing both cooperative and antagonistic interactions with one or multiple leader…
Stability of Open Multi-agent Systems over Dynamic Signed Digraphs
Pelin Sekercioglu, Angela Fontan, Dimos V. Dimarogonas
We address the synchronization problem in open multi-agent systems (OMAS) containing both cooperative and antagonistic interactions. In these systems, agents can join or leave the…
