In this paper, for a measure which is not doubling, we introduce a notion of point-wise doubling index, and calculate the point-wise doubling indices of uniform Bernoulli measures on Bedford-McMullen carpets. As an application, we show that, except a small class of Bedford-McMullen carpets, if two Bedford-McMullen carpets are bi-Lipschitz equivalent, then they have the same fiber sequence up to a permutation.", "revisions": [ { "version": "v1", "updated": "2025-01-05T03:10:16.000Z" } ], "analyses": { "subjects": [ "28A80", "26A16" ], "keywords": [ "point-wise doubling index", "bedford-mcmullen carpets", "bi-lipschitz classification", "application", "uniform bernoulli measures" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
