F-equicontinuity and an Analogue of Auslander-Yorke Dichotomy Theorem

In this paper, we introduce an ${\mathscr F}$-equi\-con\-ti\-nui\-ty and show an analogue of Auslander-Yorke dichotomy theorem for ${\mathscr F}$-sensitivity. Precisely, under the condition that $k{\mathscr F}$ is translation invariant, we prove that a transitive system is either ${\mathscr F}$-sensitive or almost $k{\mathscr F}$-equi\-con\-ti\-nuo\-us , and so generalize the result of previous work. Also we show that ${\mathscr F}$-equi\-con\-ti\-nui\-ty is preserved by an open factor map and consider the implication between ${\mathscr F}$-equi\-con\-ti\-nui\-ty and mean equi\-con\-ti\-nui\-ty.

A-coupled-expanding and distributional chaos

The concept of A-coupled-expanding map, which is one of the more natural and useful ideas generalized the horseshoe map, is well known as a criterion of chaos. It is well known that distributional chaos is one of the concepts which reflect strong chaotic behaviour. In this paper, we focus the relations between A-coupled-expanding and distributional chaos. We prove two theorems that give sufficient conditions for a strictly A-coupled-expanding map to be distributionally chaotic in the senses of two kinds, where A is an irreducible transition matrix.

Hausdorff dimension of the sets of Li-Yorke pairs for some chaotic dynamical systems including A-coupled expanding systems

In this paper we consider Hausdorff dimension of the sets of Li-Yorke pairs for some chaotic dynamical systems including $A$-coupled expanding systems. We prove that Li-Yorke pairs of $A$- coupled-expanding system under some conditions have full hausdorff dimension on the invariant set. we generalize the result of [8] on the Hausdorff dimension of Li-Yorke pairs of dynamical systems topologically conjugate to the full shift and having a self-similar invariant set to the case of dynamical system conjugated to some kind of subshifts. And Hausdorff dimension of "chaotic invariant set" for some kind of A-coupled-expanding maps is shown.
