Network dynamics with higher-order interactions: coupled cell hypernetworks for identical cells and synchrony

Abstract: Network interactions that are nonlinear in the state of more than two nodes—also known as higher-order interactions—can have a profound impact on the collective network dynamics. Here we develop a coupled cell hypernetwork formalism to elucidate the existence and stability of (cluster) synchronization patterns in network dynamical systems with higher-order interactions. More specifically, we define robust synchrony subspace for coupled cell hypernetworks whose coupling structure is determined by an underlying … Show more

“…Higher order interaction networks have found their way into various recent mathematical studies as well. We mention in particular the theoretical papers [4,5,6,7,8,9,10], which investigate synchronisation in classes of networks with non-pairwise, nonlinear interaction in their equation of motion. We also refer to the excellent surveys [11,12,13,14,15] and references therein, for an in-depth discussion of higher order networks, and numerous examples of higher order network systems arising in applications.…”

“…Note that the requirement that the functions are invariant under permutations of the inputs y imposes conditions on the coefficients a (m+1) n (z): For example, we have to have a A particular choice of interaction function still leaves some ambiguity in terms of the network; see also [9] for a more detailed discussion. First, the interaction function G (m) (z; y 1 , .…”

“…These have famously been introduced and algebraically studied in [24,25,26,27] for coupled cell networks. More recently, first advances have been made to generalise balanced partitions to network dynamical systems with higher-order interactions [9,7,28,10]. For instance in order for vertices 1 and 2 to synchronize, the partition {1, 2}, {3} needs to be balanced, meaning that any vertex in an element of the partition needs to receive the same 'kind' of inputs from any element of the partition as any other vertex in that same element.…”
