Transitive points via Furstenberg family
Abstract
Let be a topological dynamical system and be a Furstenberg family (a collection of subsets of with hereditary upward property). A point is called an -transitive one if for every nonempty open subset of ; the system is called -point transitive if there exists some -transitive point. In this paper, we aim to classify transitive systems by -point transitivity. Among other things, it is shown that is a weakly mixing E-system (resp.\@ weakly mixing M-system, HY-system) if and only if it is -point transitive (resp.\@ -point transitive, -point transitive). It is shown that every weakly mixing system is -point transitive, while we construct an -point transitive system which is not weakly mixing. As applications, we show that every transitive system with dense small periodic sets is disjoint from every totally minimal system and a system is -transitive if and only if it is weakly disjoint from every P-system.
