Abstract: |
In the paper,we study an n-dimensional complete connected and oriented hypersurface MN in Hn+1(-1) with constant mean curvature and two distinct principal curvatures,one of which is simple.By using the moving frames,we obtain that if the squared norm of second fundamental form of Mn satisfies a rigidity condition (1.3),the Mn is isometric to hyperbolic cylinder. |
Key words: hypersurfaces hyperbolic space form constant mean curvature |
