| 摘 要： | A hypersurface x: M→S^n 1 without umbilic point is called a Moebius k- order pre- isoparametric hypersurface if its Moebius form φ vanishes and k distinct eigenvalues of the Blaschke tensor A are constant. In this paper we classify all Moebius 2 - order pre-isoparametric hypersurfaces in S^4.

| Abstract: | A hypersurface x:M→ Sn + 1 without umbilic point is called a Moebius k- order pre- isoparametric hypersurface if its Moebius form φ vanishes and k distinct eigenvalues of the Blaschke tensor A are constant. In this paper we classify all Moebius 2 - order pre - isoparametric hypersurfaces in S4. |
