In general, this result provides, in some direction, a finer description of an $L^{p}$-approximation for $L^{p}$ functions on $\\mathbb{R}$.", "revisions": [ { "version": "v1", "updated": "2020-06-12T16:41:25.000Z" } ], "analyses": { "subjects": [ "60A10", "46E30", "26A24" ], "keywords": [ "sensitive random variables", "borel probability measure", "norm greater", "pre-specified real number", "finer description" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
