Electronic circuits offer the interesting opportunity to simulate at low cost most of nonlinear phenomena found in other dynamical systems. Simple electronic circuits have been designed to demonstrate complex and striking events such as period-doubling bifurcation, period-adding bifurcation, the concurrent creation and annihilation of periodic orbits, chaos, intermittency, crisis, hysteresis, and coexisting multiple attractors, and extreme multistability. Interestingly, such simple electronic circuits with extremely rich behaviors allow possible applications in science and engineering domains. In addition, these electronic circuits represent valuable tools for performing simple laboratory experiments, using off-the shelf electronic components for students learning about chaos. Consequently, the quest for the simplest circuit or differential equation that can develop chaos, symmetry and multistability represents the material of numerous publications.
The aim of this special issue is to collect contributions in simple nonlinear chaotic circuits and systems characterized by multistability and symmetry construction or destruction. Engineering application of such systems or circuits with multistability and symmetry are also welcome.
