Quadratic Killing structure Jacobi operator for real hypersurfaces in complex two-plane Grassmannians
Hyunjin Lee, Young Jin Suh, Changhwa Woo
In this paper, we introduce a notion of quadratic Killing structure Jacobi operator (simply, Killing structure Jacobi operator) and its geometric meaning for real hypersurfaces in…
Derivatives of normal Jacobi operator on real hypersurfaces in the complex quadric
Hyunjin Lee, Juan de Dios Pérez, Young Jin Suh
In \cite{S 2017}, Suh gave a non-existence theorem for Hopf real hypersurfaces in the complex quadric with parallel normal Jacobi operator. Motivated by this result, in this paper,…
Commuting Jacobi operators on Real hypersurfaces of Type B in the complex quadric
Hyunjin Lee, Young Jin Suh
In this paper, first, we investigate the commuting property between the normal Jacobi operator~ and the structure Jacobi operator~ for Hopf real hypersurfaces in t…
Real hypersurfaces in the complex quadric with Reeb parallel structure Jacobi operator
Hyunjin Lee, Young Jin Suh
In this paper, we first introduce the full express of the Riemannian curvature tensor of a real hypersurface in complex quadric from the equation of Gauss. Next we deri…
Real hypersurfaces in complex hyperbolic two-plane Grassmannians with commuting structure Jacobi operators
Hyunjin Lee, Young Jin Suh, Changhwa Woo
In this paper, we introduce a new commuting condition between the structure Jacobi operator and symmetric (1,1)-type tensor field , that is, , where or …
Semi-parallel symmetric operators for Hopf hypersurfaces in complex two-plane Grassmannians
Doo Hyun Hwang, Hyunjin Lee, Changhwa Woo
In this paper, we introduce new notions of semi-parallel shape operators and structure Jacobi operators in complex two-plane Grassmannians . By using such a…
Addendum to the paper "Hypersurfaces with Isometric Reeb Flow in Complex hyperbolic Two-Plane Grassmannians"
Hyunjin Lee, Mi Jung Kim, Young Jin Suh
We classify all of real hypersurfaces with Reeb invariant shape operator in complex hyperbolic two-plane Grassmannians , . Then it becomes…
Real hypersurfaces in complex two-plane Grassmannians with Reeb parallel Ricci tensor in generalized Tanaka-Webster connection
Hyunjin Lee, Young Jin Suh, Changhwa Woo
There are several kinds of classification problems for real hypersurfaces in complex two-plane Grassmannians . Among them, Suh classified Hopf hypersurfaces…
