WebJul 9, 2024 · Let M 4 ↪ S 5 be a closed minimal Willmore hypersurface with constant scalar curvature. If there are four distinct principle curvatures at the minimum point P of f 4, then M 4 has nonnegative scalar curvature. 5. Proof of the main theorem. Proof of Theorem 1.7. We will prove the main theorem in the following cases. http://www.numdam.org/item/ASNSP_2010_5_9_3_541_0.pdf

WebSep 3, 2024 · We derive an upper bound on the waiting time for a non star-shaped hypersurface in $\\mathbb{R}^{n+1}$ moving by Inverse Mean Curvature Flow to become star-shaped. Combining this result with an embeddedness principle for the flow, we provide an upper bound on the maximal time of existence for initial surfaces which are not … WebDec 1, 2001 · The paper considers n -dimensional hypersurfaces with constant scalar curvature of a unit sphere Sn−1 (1). havilah ravula

WebOct 7, 2024 · Yu Fu, Min-Chun Hong, Dan Yang, Xin Zhan. Biconservative hypersurfaces are hypersurfaces which have conservative stress-energy tensor with respect to the bienergy, containing all minimal and constant mean curvature hypersurfaces. The purpose of this paper is to study biconservative hypersurfaces with constant scalar curvature in a space … Webspacelike hypersurface of a Lorentzian manifold (Sn;1;g~) with pbeing the second fundamental form.

Then the boundary @M and a plane asymptotically parallel to @M serve as the WebIn this study, some identities involving the Riemannian curvature invariants are presented on lightlike hypersurfaces of a statistical manifold in the Lorentzian settings. Several inequalities characterizing lightlike hypersurfaces are obtained. These inequalities are also investigated on lightlike hypersurfaces of Lorentzian statistical space forms. havilah seguros
