Ngai and Y. Wang. While recently there has been much progress in understanding absolute continuity for homogeneous self-similar measures, this is the first improvement over the classical transversality method in the general (non-homogeneous) case. In the course of the proof, we establish new results on the dimension and Fourier decay of a class of random self-similar measures.", "revisions": [ { "version": "v1", "updated": "2017-09-15T08:08:22.000Z" } ], "analyses": { "subjects": [ "28A78", "28A80", "37A45", "42A38" ], "keywords": [ "non-homogeneous self-similar measures", "random self-similar measures", "real line", "understanding absolute continuity", "first improvement" ], "note": { "typesetting": "TeX", "pages": 45, "language": "en", "license": "arXiv", "status": "editable" } } }
