Group adaptation drives opinion dynamics in higher-order networks
Cosimo Agostinelli, Marco Mancastroppa, Alain Barrat
In modern interconnected societies, opinions and beliefs can quickly spread across large populations, giving rise to collective behaviors such as the adoption of social norms or po…
Higher-order adaptive behaviors outperform pairwise strategies in mitigating contagion dynamics
Marco Mancastroppa, Márton Karsai, Alain Barrat
When exposed to a contagion phenomenon, individuals may respond to the perceived risk of infection by adopting behavioral changes, aiming to reduce their exposure or their risk of…
Adaptive behaviors neutralize bistable explosive transitions in higher-order contagion
Marco Mancastroppa, Márton Karsai, Alain Barrat
During contagion phenomena, individuals perceiving a risk of infection commonly adapt their behavior and reduce their exposure. The effects of such adaptive mechanisms have been st…
Emerging Activity Temporal Hypergraph: a model for generating realistic time-varying hypergraphs
Marco Mancastroppa, Giulia Cencetti, Alain Barrat
Time-varying group interactions constitute the building blocks of many complex systems. The framework of temporal hypergraphs makes it possible to represent them by taking into acc…
Higher-order dissimilarity measures for hypergraph comparison
Cosimo Agostinelli, Marco Mancastroppa, Alain Barrat
In recent years, networks with higher-order interactions have emerged as a powerful tool to model complex systems. Comparing these higher-order systems remains however a challenge.…
Generating surrogate temporal networks from mesoscale building blocks
Giulia Cencetti, Alain Barrat
Surrogate networks can constitute suitable replacements for real networks, in particular to study dynamical processes on networks, when only incomplete or limited datasets are avai…
