Along the way, it is proved that any finitely generated amenable Cayley graph (or more generally, amenable unimodular random graph) can be represented in R^3 as an isometry-invariant random collection of polyhedral domains (tiles). A new technique is developed to prove indistinguishability for certain constructions, connecting this notion to factor of iid's.", "revisions": [ { "version": "v1", "updated": "2017-12-21T20:56:17.000Z" } ], "analyses": { "keywords": [ "euclidean space", "isometry-invariant random partition", "isometry-invariant random collection", "amenable unimodular random graph", "finitely generated amenable cayley graph" ], "note": { "typesetting": "TeX", "pages": 22, "language": "en", "license": "arXiv", "status": "editable" } } }
