We use this result to analyze the negative $L^2$ gradient flow of the Willmore energy plus a positive multiple of the inclosed volume. We show that initial surfaces of Willmore energy less than $8\\pi$ with positive inclosed volume converge to a round point in finite or infinite time.", "revisions": [ { "version": "v1", "updated": "2020-09-25T14:42:42.000Z" } ], "analyses": { "subjects": [ "47J35", "53A05" ], "keywords": [ "gradient flow", "helfrich functional", "application", "willmore energy plus", "inclosed volume" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
