Commuting Conditions of the k-th Cho operator with the structure Jacobi operator of real hypersurfaces in complex space forms

Konstantina PanagiotidouJuan de Dios Pérez — 2015

Open Mathematics

In this paper three dimensional real hypersurfaces in non-flat complex space forms whose k-th Cho operator with respect to the structure vector field ξ commutes with the structure Jacobi operator are classified. Furthermore, it is proved that the only three dimensional real hypersurfaces in non-flat complex space forms, whose k-th Cho operator with respect to any vector field X orthogonal to structure vector field commutes with the structure Jacobi operator, are the ruled ones. Finally, results...

Real hypersurfaces in a complex projective space with pseudo- 𝔻 -parallel structure Jacobi operator

Hyunjin LeeJuan de Dios PérezYoung Jin Suh — 2010

Czechoslovak Mathematical Journal

We introduce the new notion of pseudo- 𝔻 -parallel real hypersurfaces in a complex projective space as real hypersurfaces satisfying a condition about the covariant derivative of the structure Jacobi operator in any direction of the maximal holomorphic distribution. This condition generalizes parallelness of the structure Jacobi operator. We classify this type of real hypersurfaces.

Generalized Tanaka-Webster and Levi-Civita connections for normal Jacobi operator in complex two-plane Grassmannians

Eunmi PakJuan de Dios PérezYoung Jin Suh — 2015

Czechoslovak Mathematical Journal

We study classifying problems of real hypersurfaces in a complex two-plane Grassmannian G 2 ( m + 2 ) . In relation to the generalized Tanaka-Webster connection, we consider that the generalized Tanaka-Webster derivative of the normal Jacobi operator coincides with the covariant derivative. In this case, we prove complete classifications for real hypersurfaces in G 2 ( m + 2 ) satisfying such conditions.

Real hypersurfaces in complex space forms concerned with the local symmetry

Seon Mi LyuJuan de Dios PérezYoung Jin Suh — 2007

Czechoslovak Mathematical Journal

This paper consists of two parts. In the first, we find some geometric conditions derived from the local symmetry of the inverse image by the Hopf fibration of a real hypersurface M in complex space form M m ( 4 ϵ ) . In the second, we give a complete classification of real hypersurfaces in M m ( 4 ϵ ) which satisfy the above geometric facts.

Hopf hypersurfaces in complex two-plane Grassmannians with generalized Tanaka-Webster parallel normal Jacobi operator

Eunmi PakJuan de Dios PérezCarlos J. G. MachadoChanghwa Woo — 2015

Czechoslovak Mathematical Journal

We study the classifying problem of immersed submanifolds in Hermitian symmetric spaces. Typically in this paper, we deal with real hypersurfaces in a complex two-plane Grassmannian G 2 ( m + 2 ) which has a remarkable geometric structure as a Hermitian symmetric space of rank 2. In relation to the generalized Tanaka-Webster connection, we consider a new concept of the parallel normal Jacobi operator for real hypersurfaces in G 2 ( m + 2 ) and prove non-existence of real hypersurfaces in G 2 ( m + 2 ) with generalized Tanaka-Webster...
