New characterizations of ruled real hypersurfaces in complex projective space Pérez Jiménez, Juan De Dios Pérez López, David g-Tanaka-Webster connection Complex projective space Real hypersurface kth Cho operator Torsion operator Ruled real hypersurfaces We consider real hypersurfaces M in complex projective space equipped with both the Levi–Civita and generalized Tanaka–Webster connections. For any nonnull constant k and any symmetric tensor field of type (1, 1) L on M, we can define two tensor fields of type (1, 2) on M, LF(k) and LT(k) , related to both connections. We study the behaviour of the structure operator ϕ with respect to such tensor fields in the particular case of L= A , the shape operator of M, and obtain some new characterizations of ruled real hypersurfaces in complex projective space. 2023-09-11T09:35:17Z 2023-09-11T09:35:17Z 2023-08-10 journal article Pérez, J.d.D., Pérez-López, D.
