Perfect-fluid, generalised Robertson-Walker space-times, and Gray's decomposition
Carlo Alberto Mantica, Luca Guido Molinari, Young Jin Suh +1
We give new necessary and sufficient conditions on the Weyl tensor for generalized Robertson-Walker (GRW) space-times to be perfect-fluid space-times. For GRW space-times, we deter…
Real hypersurfaces with isometric Reeb flow in Kaehler manifolds
Jurgen Berndt, Young Jin Suh
We investigate the structure of real hypersurfaces with isometric Reeb flow in Kaehler manifolds. As an application we classify real hypersurfaces with isometric Reeb flow in irred…
Inequalities for algebraic Casorati curvatures and their applications
Mukut Mani Tripathi
The notion of different kind of algebraic Casorati curvatures are introduced. Some results expressing basic Casorati inequalities for algebraic Casorati curvatures are presented. E…
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 the complex quadric with commuting Ricci tensor
Young Jin Suh, Doo Hyun Hwang
We introduce the notion of commuting Ricci tensor for real hypersurfaces in the complex quadric . It is shown that the commuting Ricci tensor gives that t…
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…
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…
