The main feature of the proof is to overcome the propagation of smallness by a global approach using a refined parabolic frequency function method. It relies with a Carleman commutator estimate to obtain the logarithmic convexity property of the frequency function.", "revisions": [ { "version": "v1", "updated": "2021-05-27T07:42:20.000Z" } ], "analyses": { "keywords": [ "neumann boundary condition", "logarithmic convexity", "heat equation", "observation estimate", "refined parabolic frequency function method" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
