The Smale Horseshoe
摘要
The Smale horseshoeSmale horseshoe offers a model for pervasive high-dimensional nonlinear phenomena, as well as a powerful technique for proving chaos. Here in this chapter, we present the famous Smale horseshoe and show that it has a shift invariant set with respect to the two-sided shift. We first introduce the standard Smale horseshoe and then discuss the general case.
