In this paper we consider variants of this metric which in general are of higher order. We derive the geodesic equations, we show that they are well-posed under some conditions and induce a locally diffeomorphic geodesic exponential mapping. We give a condition when Ricci flow is a gradient flow for one of these metrics.", "revisions": [ { "version": "v4", "updated": "2012-12-11T09:39:45.000Z" } ], "analyses": { "subjects": [ "58D17", "58E30", "35A01" ], "keywords": [ "riemannian metrics", "sobolev metrics", "compact manifold", "higher order", "ricci flow" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 20, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1102.3347B" } } }
