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…
Real hypersurfaces in complex Grassmannians of rank two with semi-parallel structure Jacobi operator
Avik De, Tee-How Loo, Changhwa Woo
We prove that there does not exist any real hypersurface in complex Grassmannians of rank two with semi-parallel structure Jacobi operator. With this result, the nonexistence of re…
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 …
Real Hypersurfaces in complex two-plane Grassmannians with recurrent Ricci tensor
Young Jin Suh, Doo Hyun Hwang, Changhwa Woo
In this paper, we have introduced a new notion of generalized Tanaka-Webster Reeb recurrent Ricci tensor in complex two-plane Grassmannians . Next, we give…
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…
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…
Real hypersurfaces in complex two-plane Grassmannians with commuting restricted Jacobi operators
Eunmi Pak, Young Jin Suh, Changhwa Woo
In this paper, we have considered a new commuting condition, that is, \big(resp. $(\Bar{R}_Nϕ) S = S (\Bar{R}_Nϕ$)\big) between the restricted Jacobi operator…
