Heteroclinic switching between chimeras

C Bick - Physical Review E, 2018 - APS
Functional oscillator networks, such as neuronal networks in the brain, exhibit switching
between metastable states involving many oscillators. We give exact results how such …

Stability of cycling behaviour near a heteroclinic network model of Rock–Paper–Scissors–Lizard–Spock

CM Postlethwaite, AM Rucklidge - Nonlinearity, 2022 - iopscience.iop.org
The well-known game of Rock–Paper–Scissors can be used as a simple model of
competition between three species. When modelled in continuous time using differential …

Heteroclinic dynamics of localized frequency synchrony: Stability of heteroclinic cycles and networks

C Bick, A Lohse - Journal of Nonlinear Science, 2019 - Springer
Coupled populations of identical phase oscillators with higher-order interactions can give
rise to heteroclinic cycles between invariant sets where populations show distinct …

Predicting the separation of time scales in a heteroclinic network

M Voit, H Meyer-Ortmanns - Applied Mathematics and Nonlinear …, 2019 - sciendo.com
We consider a heteroclinic network in the framework of winnerless competition, realized by
generalized Lotka-Volterra equations. By an appropriate choice of predation rates we …

[PDF][PDF] From coupled networks of systems to networks of states in phase space

O Weinberger, PB Ashwin - 2018 - ore.exeter.ac.uk
Dynamical systems on graphs can show a wide range of behaviours beyond simple
synchronization-even simple globally coupled structures can exhibit attractors with …

Behaviour of trajectories near a two-cycle heteroclinic network

O Podvigina - Dynamical Systems, 2023 - Taylor & Francis
Heteroclinic networks and cycles are invariant sets comprised of interacting nodes
connected by heteroclinic trajectories. Often the sets are not asymptotically stable but attract …

Noise-constrained switching times for heteroclinic computing

FS Neves, M Voit, M Timme - Chaos: An Interdisciplinary Journal of …, 2017 - pubs.aip.org
Heteroclinic computing offers a novel paradigm for universal computation by collective
system dynamics. In such a paradigm, input signals are encoded as complex periodic orbits …

Finite switching near heteroclinic networks

S Castro, L Garrido-da-Silva - Nonlinearity, 2023 - iopscience.iop.org
We address the level of complexity that can be observed in the dynamics near a robust
heteroclinic network. We show that infinite switching, which is a path towards chaos, does …

Travelling waves and heteroclinic networks in models of spatially-extended cyclic competition

DCG Dijkema, CM Postlethwaite - Nonlinearity, 2023 - iopscience.iop.org
Dynamical systems containing heteroclinic cycles and networks can be invoked as models
of intransitive competition between three or more species. When populations are assumed …

How many points converge to a heteroclinic network in an aperiodic way?

C Bick, A Lohse - arXiv preprint arXiv:2410.11383, 2024 - arxiv.org
Homoclinic and heteroclinic connections can form cycles and networks in phase space,
which organize the global phenomena in dynamical systems. On the one hand, stability …
