On certain real hypersurfaces of quaternionic projective space

We classify certain real hypersurfaces ot a quaternionic projective space satisfying the condition tr(R(X, Y)SZ) O.

Real Hypersurfaces in Complex Projective Space Whose Structure Jacobi Operator Is of Codazzi Type

We prove the non existence of real hypersurfaces in complex projective space whose structure Jacobi operator is of Codazzi type

Real Hypersurfaces in Complex Projective Space Whose Structure Jacobi Operator Is Cyclic-Ryan Parallel

We classify real hypersurfaces in complex projective space whose structure Jacobi operator satisfies a certain cyclic condition.
