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…
Nambu-Goto Like Action for the AdS_5 x S^5 Superstrings in the Generalized Light-Cone Gauge
Hiroshi Itoyama, Takeshi Oota, Reiji Yoshioka
We reinvestigate the kappa-symmetry-fixed Green-Schwarz action in the AdS_5 x S^5 background in a version of the light-cone gauge. In the generalized light-cone gauge, the action h…
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.
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…
Comments on Equations of Motion for Pure Spinors in Even Dimensions
Takeshi Oota
A Berkovits type action for pure spinors in even dimensions is considered. The equations of motion for pure spinors are investigated by using explicit parameterizations which solve…
