We also establish a Ledrappier-Young type formula for its dimension. The general strategy of the proof is based on the argument given by Feng for the exact dimensionality of self-affine measures.", "revisions": [ { "version": "v1", "updated": "2020-07-13T11:45:59.000Z" } ], "analyses": { "subjects": [ "28A80", "37C45" ], "keywords": [ "exact dimensionality", "furstenberg measure", "ledrappier-young formula", "finite dimensional real vector space", "ledrappier-young type formula" ], "note": { "typesetting": "TeX", "pages": 43, "language": "en", "license": "arXiv", "status": "editable" } } }
