Math", "categories": [ "math.DS", "math.NT" ], "abstract": "The squarefree flow is a natural dynamical system whose topological and ergodic properties are closely linked to the behavior of squarefree numbers. We prove that the squarefree flow carries a unique measure of maximal entropy and express this measure explicitly in terms of a skew-product of a Kronecker and a Bernoulli system. Using this characterization and a number-theoretic argument, we then show that the unique maximum entropy measure fails to possess the Gibbs property.", "revisions": [ { "version": "v7", "updated": "2014-05-17T17:39:28.000Z", "comment": "18 pages. Several errors have been corrected; in particular, the proof of the Gibbs property in previous versions was incorrect. d-bar convergence of sofic approximations is also no longer necessary, and may not be provable with the present method.
