WebJul 10, 2024 · The first extension of the notion of Ollivier Ricci curvature to hypergraphs was proposed in , using a multi-marginal optimal transport problem to define curvature. Because of that, the resulting curvature in the end is an analogue of Riemannian scalar rather than Ricci curvature. Also, it does not directly apply to directed hypergraphs.
