ON A UNIVERSAL CHAOTIFICATION SCHEME IN THE SENSE OF LI-YORKE
LIChangpin, CHENGuan-Rong · 系统科学与复杂性：英文版 · 2003
This paper studies the problem of making an arbitrary discrete system chaotic, or enhancing its existing chaotic behaviors, by designing a universal controller. The only assumption is that the arbitrarily given system has a bounded first derivative in a (small) region of interest.
