Hypergraph backboning

Alec Kirkley, Helcio Felippe, Federico Malizia +1

Hypergraphs provide a natural framework for describing complex networked systems with higher-order, non-dyadic interactions. Due to their high dimensionality and often redundant st…

Emergence of cooperation in nonlinear higher-order public goods games

Jaume Llabrés, Onkar Sadekar, Federico Malizia +1

Evolutionary game theory has provided substantial contributions to explain the emergence of cooperation under unfavourable conditions in ecology, economics, and the social sciences…

Group dynamics shape contagion onsets and multistable active phases under collective reinforcement

Santiago Lamata-Otín, Federico Malizia, Leah A. Keating +4

Group-based reinforcement can induce discontinuous transitions from inactive to active phases in higher-order contagion models. However, these results are typically obtained on sta…

Unveiling the impact of cross-order hyperdegree correlations in contagion processes on hypergraphs

Andrés Guzmán, Federico Malizia, István Z. Kiss

Contagion processes in social systems often involve interactions that go beyond pairwise contacts. Higher-order networks, represented as hypergraphs, have been widely used to model…

Nested hyperedges promote the onset of collective transitions but suppress explosive behavior

Federico Malizia, Andrés Guzmán, Federico Battiston +1

Higher-order interactions can induce abrupt collective transitions, yet the microscopic mechanisms controlling macroscopic critical behavior remain unclear. Here we show that neste…

Social polarization promoted by sparse higher-order interactions

Hugo Pérez-Martínez, Santiago Lamata-Otín, Federico Malizia +3

Many social interactions are group-based, yet their role in social polarization remains largely unexplored. To bridge this gap here we introduce a higher-order framework that takes…
