The resulting heat kernel estimates are governed by the intrinsic metric induced by the speed measure. We also provide a comparison result of this metric with the usual graph distance, which is optimal in the context of the random conductance model with ergodic conductances.", "revisions": [ { "version": "v1", "updated": "2017-11-29T21:41:34.000Z" } ], "analyses": { "subjects": [ "39A12", "60J35", "60K37", "82C41" ], "keywords": [ "heat kernel estimates", "general speed measure", "intrinsic metric", "random walk", "degenerate conductances" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
