As singularities may develop before the volume goes to zero, we develop a weak level-set formulation for such flows and show that the above monotonicity is still valid. This proves the isoperimetric inequality for n <= 7. Extending this to complete, simply connected 3-dimensional manifolds with nonpositive sectional curvature, we give a new proof for the Euclidean isoperimetric inequality on such manifolds.", "revisions": [ { "version": "v1", "updated": "2006-06-27T10:10:45.000Z" } ], "analyses": { "subjects": [ "28A75", "49Q20", "53C44" ], "keywords": [ "mean curvature", "nonlinear evolution", "weak level-set formulation", "euclidean isoperimetric inequality", "normal speed equal" ], "note": { "typesetting": "TeX", "pages": 42, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2006math......6675S" } } }
