- Let's break some structures imposed by higher-order interactions! We compute how things deform and what remains when continuous symmetries are broken. For now freely available at www.aimsciences.org/article/doi/... (but also at arXiv:2408.02119).
- New paper with @math-martens.bsky.social on "Multiple timescale dynamics of network adaptation with constraints" now available Open Access in Chaos: doi.org/10.1063/5.02...
- Adaptivity is a crucial ingredient of many networked systems, but a key issue is their high-dimensionality. A dense network of N nodes has O(N^2) adaptive connections.
- We introduce constraints to the adaptive dynamics as a way to reduce dimensionality. These may be intrinsic, for example, if the adaptation rule is nondirectional. Or they may be forced by a homeostasis mechanism.

- "Higher-order phase reduction for delay-coupled oscillators beyond the phase-shift approximation" now on the arXiv at arxiv.org/abs/2510.27524.
- Lots of higher-order interactions at the joint @beyondtheedge.network and RUNES workshop at AMU in Marseille this week. Thanks to @alainbarrat.bsky.social and @lordgrilo.bsky.social!
- Happening soon with the fantastic @haharrington.bsky.social. Join us!
- Join us Tue, 30 Sept (11:00 CET) as the #BeyondTheEdge Seminar series returns after the summer break! 🎙 Prof. Heather Harrington (Oxford & MPI-CBG) 📖 Topological Data Analysis for Multiscale Biology 📍 Online → beyondtheedge.network/event/semina... #TDA #ComplexSystems #Networks
- Ever wondered how many points converge to a heteroclinic network in an aperiodic way? doi.org/10.1080/1468...
- Fun collaborative project with Istvan Z. Kiss (London) and Peter Simon to understand how higher-order interactions affect the dynamics of contagion processes now out in J Math Bio: doi.org/10.1007/s002...
- I am extremely excited that my Istvan Z. Kiss number now is one with multiplicity 2!
- Going #BeyondTheEdge in Aachen! Great fun catching up with @beyondtheedge.network colleagues at the HOOC workshop organized by M Schaub: conf.netsci.rwth-aachen.de
- Adaptive network dynamics are too high dimensional? Constrain! Or maybe adaptation may be naturally constrained to low-dimensional dynamics? Joint work with @math-martens.bsky.social now on the arXiv at arxiv.org/abs/2507.06359.
- Ancient vector fields excavated close to Dynamics Days Europe 2025 in Thessaloniki. It was a fun conference (just too short), see you in Lisbon next year!
- Maybe I should use generative AI to plot any vector field in the style of ancient nails...
- If you couple two systems with bistability between oscillations of distinct effective frequencies, you have to make them different for the distinct states to synchronize in frequency. Some theory and experiments now in Science Advances. doi.org/10.1126/scia...

- Kuramoto oscillators + inertia + symmetry = global symmetric bifurcations organizing chimeras. Work with Pete Ashwin, available open access at doi.org/10.1007/s003....
- I am intrigued by the (approximate) symmetries. In that spirit, have enjoyable holidays and all the best for 2025!

- Network science accessible even to the smallest: Stop by the Department of Mathematics at @vuamsterdam.bsky.social to pick up a copy of “Bear Networks”! Thanks to funding through BeyondTheEdge.network. Digital copies are available open access through Zenodo at doi.org/10.5281/zeno....
- Networks and coffee and networks in Tokyo. What could go wrong?
- BeyondTheEdge has a shiny new homepage at beyondtheedge.network for anything related to higher-order networks and dynamics. Time to get one bluesky as well?
- I guess it is time to set up camp at bluesky.
