Dispersal-induced survival of predators in metacommunities due to transient chaos
Samali Ghosh, Arnob Ray, Everton S. Medeiros +5
Dispersal networks critically shape the fate of ecological communities, yet the mechanisms linking connectivity and persistence remain poorly understood. We show that an interplay…
Singular fractal dimension at periodicity cascades in parameters spaces
Carlos E. P. Abreu, Joelson D. V. Hermes, Diogo Ricardo da Costa +2
In the parameter spaces of nonlinear dynamical systems, we investigate the boundaries between periodicity and chaos and unveil the existence of fractal sets characterized by a sing…
Chimera states emerging from dynamical trapping in chaotic saddles
Everton S. Medeiros, Oleh Omel'chenko, Ulrike Feudel
Nonlinear systems possessing nonattracting chaotic sets, such as chaotic saddles, embedded in their state space may oscillate chaotically for a transient time before eventually tra…
The Boundaries of Synchronization in Oscillators Networks
Everton S Medeiros, Rene O. Medrano-T, Iberê L Caldas +1
We analyze the final state sensitivity of nonlocal networks with respect to initial conditions of their units. By changing the initial conditions of a single network unit, we pertu…
Trapping Phenomenon Attenuates Tipping Points for Limit Cycles
Everton S. Medeiros, Iberê L. Caldas, Murilo S. Baptista +1
Nonlinear dynamical systems may be exposed to tipping points, critical thresholds at which small changes in the external inputs or in the systems parameters abruptly shift the syst…
Parameter Uncertainties on the Predictability of Periodicity and Chaos
E. S. Medeiros, I. L. Caldas, M. S. Baptista
Nonlinear dynamical systems, ranging from insect populations to lasers and chemical reactions, might exhibit sensitivity to small perturbations in their control parameters, resulti…
Replicate Periodic Windows in the Parameter Space of Driven Oscillators
E. S. Medeiros, S. L. T. de Souza, R. O. Medrano-T. +1
In the bi-dimensional parameter space of driven oscillators, shrimp-shaped periodic windows are immersed in chaotic regions. For two of these oscillators, namely, Duffing and Josep…
