Extreme forcing and wave dynamics in weakly nonlocally coupled excitable FitzHugh-Nagumo systems
N. I. Semenova, V. V. Semenov, A. V. Bukh
The influence of extreme external forcing on traveling-wave dynamics in an ensemble of weakly nonlocally coupled excitable FitzHugh--Nagumo systems is studied. Three types of exter…
Deterministic coherence and anti-coherence resonances in two coupled Lorenz oscillators: numerical study versus experiment
Pavel S. Komkov, Ol'ga I. Moskalenko, Vladimir V. Semenov +1
We demonstrate the deterministic coherence and anti-coherence resonance phenomena in two coupled identical chaotic Lorenz oscillators. Both effects are found to occur simultaneousl…
Synchronization of coherence resonance oscillators subject to Lévy noise
Ivan A. Korneev, Vladimir V. Semenov
Using methods of numerical simulation, we analyze the influence of Lévy noise on synchronization of excitable oscillators in the regime of coherence resonance. Three cases are und…
L{é}vy-noise-induced wavefront propagation for bistable systems
Vladimir V. Semenov
The influence of the L{é}vy noise's properties on wavefront propagation is analyzed on examples of ensembles of locally coupled bistable oscillators and a single bistable delayed-…
The impact of nonlocal coupling on deterministic and stochastic wavefront propagation in an ensemble of bistable oscillators
Vladimir V. Semenov
Based on methods of numerical simulation, the constructive role of nonlocal coupling is demonstrated in the context of wavefront propagation observed in an ensemble of overdamped b…
