“…That is, the presence of a nonperiodic transitive hyperbolic attractor implies the abundance of historic behavior! There exists an extensive bibliography about historic behavior (for instance, see [BKNRS,CV,FV,Ga,KS16,KS17,LR,Li,Ta95,Th,Ya]), in particular about the topological entropy and Hausdorff dimension of the set of points with historic behavior. Pesin and Pitskel [PP] showed that, in the full shift σ : Σ + 2 , the topological entropy of the set of with historic behavior is equal to the entropy of the whole system, i.e., h top (σ| HB(σ) ) = h top (σ) = log 2.…”
