We can obtain such a family as the angle-$\\alpha$ projections of the natural measure of the Sierpi\\'nski carpet. We present more general one-parameter families of self-similar measures $\\nu_\\alpha$, such that the set of parameters $\\alpha$ for which $\\nu_\\alpha$ is singular is a dense $G_\\delta$ set but this \"exceptional\" set of parameters of singularity has zero Hausdorff dimension.", "revisions": [ { "version": "v1", "updated": "2017-02-22T13:12:11.000Z" } ], "analyses": { "subjects": [ "28A80", "28A99" ], "keywords": [ "exact overlaps", "singularity", "zero hausdorff dimension", "general one-parameter families", "parameters" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
