Comments on “Asymptotically stable equilibrium points in new chaotic systems”

Abstract

In the commented paper ten nonlinear chaotic systems are presented. Authors state that these systems do not exhibit Shilnikov chaos. Unfortunately, this assertion is not correctly proved because they use an erroneous theorem from the literature.

Keywords

• chaotic systems
• asymptotically stable equilibrium
• non-existence of Shilnikov chaos
