On designing heteroclinic networks from graphs

P Ashwin, C Postlethwaite - Physica D: Nonlinear Phenomena, 2013 - Elsevier
Robust heteroclinic networks are invariant sets that can appear as attractors in symmetrically
coupled or otherwise constrained dynamical systems. These networks may have a …

Computation by switching in complex networks of states

F Schittler Neves, M Timme - Physical review letters, 2012 - APS
Complex networks of dynamically connected saddle states persistently emerge in a broad
range of high-dimensional systems and may reliably encode inputs as specific switching …

On the occurrence of stable heteroclinic channels in Lotka–Volterra models

C Bick, MI Rabinovich - Dynamical Systems, 2010 - Taylor & Francis
The Lotka–Volterra (LV) equations can be used to model the behaviour of complex systems
in nature. Trajectories in a stable heteroclinic channel (SHC) describe transient dynamics …

Controlled perturbation-induced switching in pulse-coupled oscillator networks

FS Neves, M Timme - Journal of Physics A: Mathematical and …, 2009 - iopscience.iop.org
Pulse-coupled systems such as spiking neural networks exhibit nontrivial invariant sets in
the form of attracting yet unstable saddle periodic orbits where units are synchronized into …

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 …

Effect of node-degree correlation on synchronization of identical pulse-coupled oscillators

MD LaMar, GD Smith - Physical Review E—Statistical, Nonlinear, and Soft …, 2010 - APS
We explore the effect of correlations between the in and out degrees of random directed
networks on the synchronization of identical pulse-coupled oscillators. Numerical …

Resonance and fractal geometry

HW Broer - Acta applicandae mathematicae, 2012 - Springer
The phenomenon of resonance will be dealt with from the viewpoint of dynamical systems
depending on parameters and their bifurcations. Resonance phenomena are associated to …

Breakdown of order preservation in symmetric oscillator networks with pulse-coupling

H Kielblock, C Kirst, M Timme - Chaos: An Interdisciplinary Journal of …, 2011 - pubs.aip.org
Symmetric networks of coupled dynamical units exhibit invariant subspaces with two or more
units synchronized. In time-continuously coupled systems, these invariant sets constitute …

Unstable attractors: existence and stability indices

A Lohse - Dynamical Systems, 2015 - Taylor & Francis
We show that unstable attractors do not exist for smooth invertible dynamics. In systems
lacking these properties, we draw simple conclusions about their stability indices and look at …
