The purpose of this paper is to give a characterization of ruled hypersurfaces and homogeneous real hypersurfaces of type (A₀), (A₁), and (B) in non-flat complex space forms by using the second covariant derivatives of the shape operators.

The purpose of this paper is to give a new and simple proof of the classification theorem of D’Atri- and C-type hypersurfaces in a non-flat complex space form given by Cho and Vanhecke [3]. We use a homogeneous structure tensor on a real hypersurfa
