Higher-Order Interactions

Dynamics on hypergraphs

Do higher-order interactions promote synchronization? Should we use hypergraphs or simplicial complexes when modeling systems with higher-order interactions?

Can higher-order interactions affect linear stability and basin stability differently?

Hypergraphs from dynamics

Can we infer causal hypergraphs from time-series data in a model-free fashion? How important are higher-order interactions in the brain?
