Title HOPF HYPERSURFACES WITH WEAKLY CONSTANT CURVATURE IN THE COMPLEX PROJECTIVE SPACE Type of Research Presentation Keywords Hopf hypersurfaces, complex projective space, weakly constant curvature Abstract In this paper, we study isoparametric Hopf hypersur- faces in the complex projective space CPn such that the structural vector eld is principal and the sectional curvature is weakly con- stant.
