Generalized Kerr-NUT-de Sitter metrics in all dimensions
Tsuyoshi Houri, Takeshi Oota, Yukinori Yasui
We classify all spacetimes with a closed rank-2 conformal Killing-Yano tensor. They give a generalization of Kerr-NUT-de Sitter spacetimes. The Einstein condition is explicitly sol…
Separability of Dirac equation in higher dimensional Kerr-NUT-de Sitter spacetime
Takeshi Oota, Yukinori Yasui
It is shown that the Dirac equations in general higher dimensional Kerr-NUT-de Sitter spacetimes are separated into ordinary differential equations.
Boundary Value Problem for Black Rings
Yoshiyuki Morisawa, Shinya Tomizawa, Yukinori Yasui
We study the boundary value problem for asymptotically flat stationary black ring solutions to the five-dimensional vacuum Einstein equations. Assuming the existence of two additio…
Closed conformal Killing-Yano tensor and Kerr-NUT-de Sitter spacetime uniqueness
Tsuyoshi Houri, Takeshi Oota, Yukinori Yasui
We study spacetimes with a closed conformal Killing-Yano tensor. It is shown that the D-dimensional Kerr-NUT-de Sitter spacetime constructed by Chen-Lu-Pope is the only spacetime a…
Closed conformal Killing-Yano tensor and geodesic integrability
Tsuyoshi Houri, Takeshi Oota, Yukinori Yasui
Assuming the existence of a single rank-2 closed conformal Killing-Yano tensor with a certain symmetry we show that there exist mutually commuting rank-2 Killing tensors and Killin…
