"Free yourself with constraints" is a good summary of the work.

Multiple Timescale Dynamics of Network Adaptation with Constraints Adaptive network dynamical systems describe the co-evolution of dynamical quantities on the nodes as well as dynamics of the network connections themselves. For dense networks of many nodes, the resul...

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...

Can a network be physically be a graph but effectively be a hypergraph? Tiago Pereira is speaking about emergent hypernetworks in the focus session β€œNetwork Dynamical Systems” at @netsciconf.bsky.social.

You've got friends round for coffee and cake. There are seven of you. Trouble is, you've made a square cake. How do you make sure everyone receives an equal share?

Dominic has his cake and they all eat it.

Do we know the number of neurons in the human brain?

A typical value cited in the literature is 86 billion.

However, as I argue in this essay, the data does not justify this number and we do not have yet a satisfactory answer
