摘要 讨论了anti-de Sitter空间中类空超曲面的第K平均曲率,并利用积分公式得到全脐超曲面的分类。 We consider the Sk$-th mean curvature for spacelike hypersurfaces, which is a gen- eralization of the usual mean curvature. By using an integral formula of Minkowski type for compact spacelike hypersurfaces in H1 n+1 , we introduce some characterizations of totally umbili- cal hypersurfaces.
