On Conjugacy Invariants of $D_{\infty }$-Topological Markov Chains

Abstract

A $D_{\infty }$-topological Markov chain can be represented by a pair of zero-one square matrices, which is called a flip pair. We introduce the concepts of $D_{\infty }$-strong shift equivalence and $D_{\infty }$-shift equivalence, which are equivalence relations between flip pairs. We investigate the relationships between the existence of a $D_{\infty }$-conjugacy, the existence of a $D_{\infty }$-strong shift equivalence, the existence of a $D_{\infty }$-shift equivalence and the coincidence of the Lind zeta functions.
