In this paper, we report the discovery of some novel dynamical scenarios for quasi-periodic
shrimp-shaped structures embedded within chaotic phases in bi-parameter space of a …

We describe some remarkable continuous deformations which create and destroy peaks in
periodic oscillations of the Mackey–Glass equation, a paradigmatic example of a delayed …

We report self-similar properties of periodic structures remarkably organized in the two-
parameter space for a two-gene system, described by two-dimensional symmetric map. The …

A four-dimensional four-parameter Chua model with cubic nonlinearity is studied applying
numerical continuation and numerical solutions methods. Regarding numerical solution …

We investigate the dynamical behavior of a non-ideal Duffing oscillator, a system composed
of a mass–spring–pendulum driven by a DC motor with limited power supply. To identify …

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 …

We reveal the existence of a new codimension-1 curve that involves a topological change in
the structure of the chaotic invariant sets (attractors and saddles) in generic three …

This work reports two-dimensional parameter space plots, concerned with a three-
dimensional Hopfield-type neural network with a hyperbolic tangent as the activation …

We report numerical results on the existence of periodic structures embedded in chaotic and
hyperchaotic regions on the Lyapunov exponent diagrams of a 4-dimensional Chua system …

We report results of a numerical investigation on two-dimensional parameter-spaces of a set
of four autonomous, seven-parameter, first-order ordinary differential equations, which …
