Fantastic, well deserved.

Simply: The dynamics themselves do not go away, but making things more generic helps understand how they organize the dynamics more generally.

Not the interactions themselves. Sometimes they are just too special and give rise to extra symmetries.

Dynamics on invariant tori emerging through forced symmetry breaking in phase oscillator networks We consider synchrony patterns in coupled phase oscillator networks that correspond to invariant tori. For specific nongeneric coupling, these tori are equilibria relative to a continuous symmetry act...

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).

A summary of the results are now also part of a @oxfordmathematics.bsky.social Research Case Study: www.maths.ox.ac.uk/node/74552

Higher-order phase reduction for delay-coupled oscillators beyond the phase-shift approximation Network interactions between dynamical units are often subject to time delay. We develop a phase reduction method for delay-coupled oscillator networks. The method is based on rewriting the delay-diff...

Reducing the dimensions of adaptive networks Framework for decreasing the dimensionality of complex systems facilitates analysis of complexity.

The nice summary "Reducing the dimensions of adaptive networks" for a broader audience was published alongside the paper at doi.org/10.1063/10.0...

This motivates new mathematical insights into the multiple time scale dynamics of adaptive networks. And opens up questions how constraints and adaptive dependency is realized in real world adaptive networks.

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.

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.

Multiple timescale dynamics of network adaptation with constraints Adaptive network dynamical systems describe the co-evolution of dynamical quantities on the nodes and the dynamics of the network connections themselves. For de

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!

How many points converge to a heteroclinic network in an aperiodic way? Homoclinic and heteroclinic connections can form cycles and networks in phase space, which organize global phenomena in dynamical systems. On the one hand, stability notions for (omni)cycles give i...

Adaptive network dynamics are too high dimensional? Constrain! Or maybe adaptation may be naturally constrained to low-dimensional dynamics? Joint work with

Frequency synchronization induced by frequency detuning Analyses and experiments on multistable networks show that frequency detuning can promote synchronization.

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...
