Eduardo Jorquera Fundamenta Mathematicae 204 (2009), 177-187 MSC: 20B27, 37A35, 37C85, 37E10. DOI: 10.4064/fm204-2-6

Abstract

We show that for a finitely generated group of $C^2$ circle diffeomorphisms, the entropy of the action equals the entropy of the restriction of the action to the non-wandering set.
