A characterization of a certain real hypersurface of the complex projective space


Let M be a geodesic hypersphere or a tube of radius r over a totally geodesic CP<sup>k</sup> (1≤ k ≤ n-2, 0 < r < 𝜋/2) in a complex projective space CP<sup>n</sup>(4). We characterize M by using specific properties of the tensor field T of type (1,2) defined by
