Abstract
In this paper, we first discuss almost periodic points in a compact dynamical system with the weak specification property. On the basis of this discussion, we draw two conclusions: (i) the weak specification property implies a dense Mycielski uniform distributionally scrambled set; (ii) the weak specification property and a fixed point imply a dense Mycielski uniform invariant distributionally scrambled set. These conclusions improve on some of the latest results concerning the specification property, and give a final positive answer to an open problem posed in [P. Oprocha, Invariant scrambled sets and distributional chaos, Dyn. Syst. 24 (2009), 31–43].
