Continuous Orbit Equivalence

摘要

The notion of continuous orbit equivalence in one-sided topological Markov shifts is introduced, and its basic properties are presented. The continuous full group \(\Gamma _A\) of a one-sided topological Markov shift \((X_A,\sigma _A)\) is introduced and proved to be a countably infinite non-amenable discrete group. It is regarded as a generalization of Higman–Thompson groups.
