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…

Isometric Reeb flow in complex hyperbolic quadrics

Young Jin Suh

We classify real hypersurfaces with isometric Reeb flow in the complex hyperbolic quadrics $Q^{*}^{m} = S O_{2, m}^{o} / S O_{m} S O_{2}$ , $m \geq 3$ . We show that $m$ is even, say $m = 2 k$ ,…

Real hypersurfaces in complex two-plane Grassmannians with GTW Reeb Lie derivative structure Jacobi operator

Eunmi Pak, Gyu Jong Kim, Young Jin Suh

Using generalized Tanaka-Webster connection, we considered a real hypersurface $M$ in a complex two-plane Grassmannian $G_{2} (C^{m + 2})$ when the GTW Reeb Lie derivative of…

Generalized Tanaka-Webster Parallel Ricci tensor in complex two-plane Grassmannians

Juan de Dios Pérez, Young Jin Suh

We prove the non-existence of Hopf real hypersurfaces in complex two-plane Grassmannians whose Ricci tensor is parallel with respect to the generalized Tanaka-Webster connection.

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 $M$ with Reeb invariant shape operator in complex hyperbolic two-plane Grassmannians $S U_{2, m} / S (U_{2} \cdot U_{m})$ , $m \geq 2$ . 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 $G_{2} (C^{m + 2})$ . Among them, Suh classified Hopf hypersurfaces…
