Our proof is based on a decomposition of the underlying functional space in terms of radial processes and spherical harmonics.", "revisions": [ { "version": "v1", "updated": "2021-03-12T13:48:33.000Z" } ], "analyses": { "subjects": [ "60G15", "60G60", "60J65" ], "keywords": [ "continuum gaussian free field", "characterisation", "dimensions", "usual domain markov property", "dimensional gaussian free field" ], "note": { "typesetting": "TeX", "pages": 12, "language": "en", "license": "arXiv", "status": "editable" } } }
