Lower-dimensional chaotic systems are easily implementable and cost-effective, therefore,
more desirable for practical considerations. Not only can such systems preserve basic …

This paper introduces a two-dimensional autonomous mega-stable dynamical system with
trigonometric nonlinearities. The nonlinearity of this system is induced by tangent hyperbolic …

Benefiting from trigonometric and hyperbolic functions, a nonlinear megastable chaotic
system is reported in this paper. Its nonlinear equations without linear terms make the …

In this paper, a megastable system is designed with particular formation of attractors. It has
two formations of attractors: the inner ones with a smaller amplitude, and the outer ones with …
