In this review, we categorize chaotic systems with special properties in their equilibrium into
eight groups: Systems with no equilibrium (NE), systems with stable equilibrium (SE) …

Four-dimensional chaotic systems are a very interesting topic for researchers, given their
special features. This paper presents a novel fractional-order four-dimensional chaotic …

Nowadays, chaotic systems are attracting considerable attention due to their special
features. The aim of this paper is to study a four-dimensional system that lacks any …

By introducing a flux‐controlled memristor model with absolute value function, a 5D
multistable four‐wing memristive hyperchaotic system (FWMHS) with linear equilibrium …

Today, four-dimensional chaotic systems are attracting considerable attention because of
their special characteristics. This paper presents a non-equilibrium four-dimensional chaotic …

In this work, a new fractional-order chaotic system with a single parameter and four
nonlinearities is introduced. One striking feature is that by varying the system parameter, the …

In this paper, we introduce a new chaotic system that is used for an engineering application
of the signal encryption. It has some interesting features, and its successful implementation …

Discovering unknown aspects of non-equilibrium systems with hidden strange attractors is
an attractive research topic. A novel quadratic hyperjerk system is introduced in this paper. It …

In this paper, we introduce a new two-dimensional nonlinear oscillator with an infinite
number of coexisting limit cycles. These limit cycles form a layer-by-layer structure which is …

In this paper, a new multi-character dynamical system is proposed. It has chaotic and hyper-
chaotic attractors without any equilibrium, with a line of equilibria or with unstable …
