CR-HYPERSURFACES OF THE SIX-DIMENSIONAL SPHERE
摘要
We proved that there does not exist a proper CR-hypersurface of S^6 with parallel second fundamental form. As a result of this we showed that S^6 does not admit a proper CR-totally umbilical hypersurface. We also proved that an Einstein proper CR-hypersurface of S^6 is an extrinsic sphere.
