The proof relies on Shmerkin's recent result on the $L^{q}$ dimension of self-similar measures. We also use the same method to give results on convolutions and orthogonal projections of ergodic measures projected onto self-similar sets.", "revisions": [ { "version": "v1", "updated": "2019-08-01T08:49:28.000Z" } ], "analyses": { "subjects": [ "28A78", "37C45" ], "keywords": [ "self-similar sets", "shift invariant ergodic measures", "exponential separation condition", "orthogonal projections", "self-similar measures" ], "note": { "typesetting": "TeX", "pages": 13, "language": "en", "license": "arXiv", "status": "editable" } } }
