In this equation, there exists a function $f$ on the manifold that satisfies the following $$ (1+f){\\rm Ric} = Ddf + \\frac{nf +n-1}{n(n-1)}sg. $$ It has been conjectured that if $(g, f)$ is a solution of the critical point equation, then $g$ is Einstein and so $(M, g)$ is isometric to a standard sphere. In this paper, we show that this conjecture is true if the given Riemannian metric has positive isotropic curvature.", "revisions": [ { "version": "v1", "updated": "2021-03-29T10:35:23.000Z" } ], "analyses": { "subjects": [ "53C25", "53C20" ], "keywords": [ "positive isotropic curvature", "besse conjecture", "constant scalar curvature metrics", "total scalar curvature functional", "critical point equation arises" ], "note": { "typesetting": "TeX", "pages": 21, "language": "en", "license": "arXiv", "status": "editable" } } }
