Abstract

Given a dynamical system (X,G)(X,G), the centralizer C(G)C(G) denotes the group of all homeomorphisms of XX which commute with the action of GG. This group is sometimes called the automorphism group of the dynamical system (X,G)(X,G). In this note, we generalize the construction of Bulatek and Kwiatkowski (1992) to Zd\mathbb Z^d-Toepltiz systems by identifying a class of Zd\mathbb Z^d-Toeplitz systems that have trivial centralizers. We show that this class of Zd\mathbb Z^d-Toeplitz with trivial centralizers contains systems with positive topological entropy.
