Abstract
This paper defines and discusses the dimension notion of topological slow entropy of any subset for \({{\mathbb {Z}}}^d-\)actions. Also, the notion of measure-theoretic slow entropy for \({\mathbb {Z}}^d-\)actions is presented, which is modified from Brin and Katok (Geometric Dynamics, Springer, Berlin 1983). Relations between Bowen topological entropy Bowen (Trans Am Math, 184:125–136, 1973), and topological slow entropy are studied in this paper, and several examples of the topological slow entropy in a symbolic system are given. Specifically, a variational principle is proved.
