报告题目：Chaotic Systems with Particular Characteristics
摘要：One characteristic of nonlinear science is chaos. Particularly in dynamical systems, the behavior of systems like periodicity, fixed points, and chaos has developed into an essential mathematics component. Chaotic systems are sophisticated nonlinear dynamical systems that have drawn many studies. It can be demonstrated that the presence of at least three state variables (third-order systems) and one nonlinear factor is a prerequisite for chaotic behavior in autonomous dynamical systems. Practical considerations are preferred because lower-dimensional chaotic systems are more affordable and more straightforward to construct. Not only are elegant chaotic systems lower-dimensional, but they also have the fewest and most basic nonlinear terms. Simple mathematical equations, different kinds of equilibria, symmetry, conservativity, coexisting attractors, multistability, hidden attractors, multi-scroll (multi-wing) attractors, amplitude control, variable boosting, and even hyper-chaotic dynamics are some of the unique characteristics that these systems may have in addition to their ability to maintain fundamental chaotic properties.
