Recently there has been increasing interest in finding and studying rare examples of simple chaotic systems such as those in which there are no equilibria or in which any existing equilibria are stable [1-7]. They belong to a new defined category of chaotic systems which is called “chaotic systems with hidden attractor” [8-9]. However they are all about chaotic flows and I haven’t seen any similar work about chaotic maps. Does anybody know about a chaotic map with no equilibria or only stable equilibria?
