New on the arxiv: “Graphs are maximally expressive for higher-order interactions” arxiv.org/abs/2602.16937 We clarify central misconceptions in the recent literature on "higher-order networks". w/ @piratepeel.bsky.social , @manlius.bsky.social, and @thilogross.bsky.social Explainer 🧵: 1/N

Use whatever abstraction you find more useful or convenient! We're not saying that hypergraphs are bad or useless. We're just criticizing the unfounded claim that they are required to represent multivariate interactions.

Very happy to be part of this project. My take on it is, hypergraph or network can describe the same systems and yield the same phenomena. The decision really comes down to if you want to work with matrices or higher-order tensors to explore these phenomena.

New preprint w/ @tiago.skewed.de, @manlius.bsky.social & @thilogross.bsky.social! Graph edges define the interaction domain — functional form is free Hyperedges constrain by grouping nodes into subsets: special case, not a generalisation Multilayer graphs represent any hypergraph — not vice versa

I have also written for you a short semi-technical piece on #ComplexityThoughts about this: open.substack.com/pub/manlius/... Enjoy!

Higher-order links and broken standards

The balance in the Force has been restored

Maybe it’s time we stop calling graphs “pairwise”. Multivariate coupling functions include HO interactions by design, hyperedges are optional. Under the order-decomposability assumption, the same node-level dynamics can be written as infinitely many equivalent multilayer (“gauge”) models. 1/

Out now: "Gender differences in collaboration and career progression in physics" we use collaboration #networks to identify differences between women and men in collaboration and career progression in physics. Work with Mingrong She, Jan Bachmann and Fariba Karimi.

And we're done! Goodbye everyone, safe journeys home!

When I thought it'd be a party hosting #NetSci2025 in Maastricht I didn't think it would manifest so literally 🥂🎶🕺

Thanks to everyone who helped us put this whole event together. Thanks to everyone who joined us this week. Seeing so many happy network scientists was truly wonderful!

And that is it!! Thank you so much the #NetSci2025 organizers for such a great experience this week!!

The lovely Netplace people and their wonderful energy and ideas created some great opportunities for connections and engagement. It was really nice to work with them!

Congratulations for these lovely contributions!

#netsci2025 awards! Congrats to all winners!

Time to storm the castle!

This is actually just retaliation to mess with all those network scientists who've been using their badges for "free" train rides. #NetSci2025

Zachary Neal@zpneal.bsky.social · last yr.

Ironic that transit from #NetSci2025 @netsciconf.bsky.social is disrupted due to failure of a high-betweenness node.

I came at #NetSci2025 to present but I ended up being presented. Thanks @piratepeel.bsky.social

#netsci2025 is officially open! @piratepeel.bsky.social explaining the advanced AI used to make badges find their owners

Starting the SINM satellite at @netsciconf.bsky.social with an exciting talk by Daichi Kuroda!

No time to summarize 2.5h lecture in a few posts Some of the most important messages can be found by reading #ComplexityThoughts at manlius.substack.com and by reading our paper w/ @piratepeel.bsky.social @tiago.skewed.de at www.nature.com/articles/s41... If you are in Maastricht, say hello /fin

It was a pleasure to lecture at the @netsciconf.bsky.social for an interested & interactive audience. What's a model? Why do we model? Is our network a network? Can we restore broken and forgotten links? I will post on #ComplexityThoughts about this lecture, which I have enjoyed to prepare. 🧵 1/

The alarm you just heard at #NetSci2025 is the Dutch testing their emergency alert system that happens every first Monday of the month at 12 noon. THE WORLD IS NOT ENDING (yet)

The quiet before the storm. Good morning #NetSci2025

Not long now... @netsciconf.bsky.social
