New paper: "The Cost of Representing Higher-Order Dynamics on Graphs" Can graphs represent group interactions? Yes, but graphs pay a parsimony cost when compared to using hypergraphs. Addresses recent work by Peixoto et al., Moutuou, and Lacasa. scroll.press/2026/graph-hypergraph-dynamics-cost

Diagram with two panels. Left panel labeled "As structures" shows nested ellipses: DynHyp (outermost) contains DynHyp_focal, which contains DynGraph, which contains DynHyp_flat (dashed). DynHyp_NFS sits separately inside DynHyp. Right panel labeled "As trajectories" shows a single ellipse: DynGraph = DynHyp. The structural hierarchy on the left collapses to equivalence on the right.

What if your paper's figures were interactive? I rebuilt one of my papers as a web page. Drag a slider: control the threshold for graph reconstruction. Click a button: run link prediction. Check it out: scroll.press/2026/glee
