Competing heterogeneities shape ordering via higher-order interactions
Gangmin Son, Federico Battiston, Deok-Sun Lee +1
Higher-order interactions admit richer structural heterogeneity than pairwise networks. To understand how heterogeneity impacts collective phenomena we develop a framework based on…

Optimality in group-driven social dynamics on hypergraphs
Jihye Kim, Deok-Sun Lee, K. -I. Goh
We explore the role of intrinsic structural properties of hypergraphs in governing group-driven social dynamics with social reinforcement. First, we analyze simplicial contagion dy…

Phase Transitions in the Simplicial Ising Model on Hypergraphs
Gangmin Son, Deok-Sun Lee, Kwang-Il Goh
We study the phase transitions in the simplicial Ising model on hypergraphs, in which the energy within each hyperedge (group) is lowered only when all the member spins are unanimo…
