These results form three of the five claims required in our earlier paper (arXiv:0805.4666) to prove global regularity for such wave maps. (The conditional claim of large data well-posedness is one of the remaining claims required in that paper.)", "revisions": [ { "version": "v2", "updated": "2009-08-06T00:09:47.000Z" } ], "analyses": { "subjects": [ "35L70" ], "keywords": [ "energy class", "global regularity", "self-similar solutions", "stationary", "harmonic map heat flow" ], "note": { "typesetting": "TeX", "pages": 77, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008arXiv0806.3592T" } } }
