In the particular case of minimal $\\mathbb{Z}^d$-odometers, we show that their bounded speedups must again be odometers but, contrary to the 1-dimensional case, they need not be conjugate, or even isomorphic, to the original.", "revisions": [ { "version": "v1", "updated": "2021-03-02T20:23:33.000Z" } ], "analyses": { "subjects": [ "37B05" ], "keywords": [ "topological speedups", "associated unital dimension groups", "orbit equivalence classes", "invariant borel measures", "cantor systems" ], "note": { "typesetting": "TeX", "pages": 37, "language": "en", "license": "arXiv", "status": "editable" } } }
