\(\phi\)-sectional curvatures of homogeneous real hypersurfaces in a complex projective space (Q6062815)

This paper addresses the computation of $\phi$-sectional curvatures for certain families of homogeneous real hypersurfaces in a complex projective space. Drawing on previous work, the author classifies these hypersurfaces into six types, providing a comprehensive framework for understanding their geometric properties. The strength of the paper lies in calculating the maximum and minimum values of $\phi$-sectional curvatures for homogeneous real hypersurfaces of types (C), (D), and (E) according to his classification.
