Abstract

In this study, we introduce a H-strictly convex hypersurface in the 6-dimensional unitary de Sitter space  and give a lower bound approximation for the Ricci curvature of such  hypersurfaces under some appropriate conditions.

 

Key words: Ricci curvature, H-convex submanifold, hypersurface, de Sitter space.
