该文对anti—deSitter空间H^n+1 1中的紧致类空超曲面建立了积分公式,并应用它们在常高阶平均曲率的条件下讨论了H^n+1 1中紧致类空超曲面的全脐问题.
In this paper, the authors develop some integral formulas for compact space-like hypersurfaces in anti-de Sitter spacetime H^n+1 1 and apply them to characterize the totally umbilical ones in H^n+1 1 as the only compact space-like hypersurfaces with constant higher order mean curvature under some appropriate hypothesis.
