Consider a non-empty set of subsets of . An operator on satisfies property if for any non-empty open set in , there exists such that . Let the collection of sets in with positive upper Banach density. Our main result is a characterization of sequence of operators satisfying property , for which we have used a strong result of Bergelson and Mccutcheon in the vein of Szemer'{e}di’s theorem. It turns out that operators having property satisfy a kind of recurrence described in terms of essential idempotents of . We will also discuss the case of weighted backward shifts. Finally, we obtain a characterization of reiteratively hypercyclic operators.
