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…
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…
Adaptive Online Optimization for Microgrids with Renewable Energy Sources
Wouter J. A. van Weerelt, Angela Fontan, Nicola Bastianello
In this paper we propose a novel adaptive online optimization algorithm tailored to the management of microgrids with high renewable energy penetration, which can be formulated as…
Collective decision-making dynamics in hypernetworks
Angela Fontan, Silun Zhang
This work describes a collective decision-making dynamical process in a multiagent system under the assumption of cooperative higher-order interactions within the community, modele…
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…
Stability of Open Multi-agent Systems over Dynamic Signed Graphs
Pelin Sekercioglu, Angela Fontan, Dimos V. Dimarogonas
This paper addresses the bipartite consensus-control problem in open multi-agent systems containing both cooperative and antagonistic interactions. In these systems, new agents can…
What influences occupants' behavior in residential buildings: An experimental study on window operation in the KTH Live-In Lab
Mahsa Farjadnia, Angela Fontan, Alessio Russo +2
Window-opening and window-closing behaviors play an important role in indoor environmental conditions and therefore have an impact on building energy efficiency. On the other hand,…
Multi-agent consensus over time-invariant and time-varying signed digraphs via eventual positivity
Angela Fontan, Lingfei Wang, Yiguang Hong +2
Laplacian dynamics on signed digraphs have a richer behavior than those on nonnegative digraphs. In particular, for the so-called "repelling" signed Laplacians, the marginal stabil…
History Data Driven Distributed Consensus in Networks
Venkatraman Renganathan, Angela Fontan, Karthik Ganapathy
The association of weights in a distributed consensus protocol quantify the trust that an agent has on its neighbors in a network. An important problem in such networked systems is…
On the properties of Laplacian pseudoinverses
Angela Fontan, Claudio Altafini
The pseudoinverse of a graph Laplacian is used in many applications and fields, such as for instance in the computation of the effective resistance in electrical networks, in the c…
The role of frustration in collective decision-making dynamical processes on multiagent signed networks
Angela Fontan, Claudio Altafini
In this work we consider a collective decision-making process in a network of agents described by a nonlinear interconnected dynamical model with sigmoidal nonlinearities and signe…
Interval Consensus for Multiagent Networks
Angela Fontan, Guodong Shi, Xiaoming Hu +1
The constrained consensus problem considered in this paper, denoted interval consensus, is characterized by the fact that each agent can impose a lower and upper bound on the achie…
Multiequilibria analysis for a class of collective decision-making networked systems
Angela Fontan, Claudio Altafini
The models of collective decision-making considered in this paper are nonlinear interconnected cooperative systems with saturating interactions. These systems encode the possible o…
