Evolutionary dynamics of higher-order interactions in social networks

Understand

We live and cooperate in networks.

• However, links in networks only allow for pairwise interactions, thus making the framework suitable for dyadic games, but not for games that are played in groups of more than two players.
• Here, we study the evolutionary dynamics of a public goods game in social systems with higher-order interactions.
• First, we show that the game on uniform hypergraphs corresponds to the replicator dynamics in the well-mixed limit, providing a formal theoretical foundation to study cooperation in networked groups.
