Nature Physics perspective: higher-order interactions beat pairwise networks for complex systems
burny_tech · x · 2026-10-01
A widely cited Nature Physics perspective (Battiston et al., 2021, 1,000+ citations) argues that complex networks are inherently limited to pairwise interactions, while real-world systems involve group interactions of three or more units. The authors propose hypergraphs and simplicial complexes as better tools to map the true organization of such systems and review the physics of higher-order interaction dynamics, a line of work relevant to hypergraph-based representation learning in AI.
