Hypergraphs provide a powerful mathematical framework for representing complex systems in which interactions occur not just between pairs of entities, but among groups. This advanced representation is particularly valuable for modeling diffusion, the spread of information or behaviors, through complex systems. Diffusion models play a key role in diverse fields such as biology, social science, and finance. On the…
