Apart from establishing basic results, we introduce a natural operation called {\\em pinning} on the space of limit objects and show how this operation yields a canonical cut metric approximation to a given probability distribution akin to the weak regularity lemma for graphons. We also establish the cut metric continuity of basic operations such as taking product measures.", "revisions": [ { "version": "v1", "updated": "2019-05-31T13:55:16.000Z" } ], "analyses": { "subjects": [ "60C05" ], "keywords": [ "limit objects", "cut metric continuity", "discrete probability distributions", "weak regularity lemma", "probability distribution akin" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
