We use DeTurck's trick to rewrite conformal Ricci flow as a strong parabolic-elliptic partial differential equations. Then we prove short time existences for conformal Ricci flow on compact manifolds as well as on asymptotically flat manifolds. We show that Yamabe constant is monotonically increasing along conformal Ricci flow on compact manifolds. We also show that conformal Ricci flow is the gradient flow for the ADM mass on asymptotically flat manifolds.", "revisions": [ { "version": "v1", "updated": "2011-09-25T17:50:16.000Z" } ], "analyses": { "subjects": [ "53C25" ], "keywords": [ "asymptotically flat manifolds", "strong parabolic-elliptic partial differential equations", "study conformal ricci flow", "rewrite conformal ricci flow", "compact manifolds" ], "note": { "typesetting": "TeX", "pages": 22, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1109.5377L" } } }
