Symmetry operators for the conformal wave equation in rotating black hole spacetimes
Finnian Gray, Tsuyoshi Houri, David Kubiznak +1
We present covariant symmetry operators for the conformal wave equation in the (off-shell) Kerr-NUT-AdS spacetimes. These operators, that are constructed from the principal Killing…
The First Order Symmetry Operator on Gravitational Perturbations in the 5-dimensional Myers-Perry Spacetime with Equal Angular Momenta
Masataka Tsuchiya, Tsuyoshi Houri, Chul-Moon Yoo
It has been revealed that the first order symmetry operator for the linearized Einstein equation on a vacuum spacetime can be constructed from a Killing-Yano 3-form. This might be…
Hidden symmetry and the separability of the Maxwell equation on the Wahlquist spacetime
Tsuyoshi Houri, Norihiro Tanahashi, Yukinori Yasui
We examine hidden symmetry and its relation to the separability of the Maxwell equation on the Wahlquist spacetime. After seeing that the Wahlquist spacetime is a type-D spacetime…
On symmetry operators for the Maxwell equation on the Kerr-NUT-(A)dS spacetime
Tsuyoshi Houri, Norihiro Tanahashi, Yukinori Yasui
We focus on the method recently proposed by Lunin and Frolov-Krtouš-Kubizňák to solve the Maxwell equation on the Kerr-NUT-(A)dS spacetime by separation of variables. In their meth…
Separability of Maxwell equation in rotating black hole spacetime and its geometric aspects
Tsuyoshi Houri, Norihiro Tanahashi, Yukinori Yasui
Recently a new formalism for perturbations of Maxwell's equations on the background of the Kerr-NUT-(A)dS spacetime was proposed, with which the equations are reduced to a equation…
On Integrability of the Geodesic Deviation Equation
Marco Cariglia, Tsuyoshi Houri, Pavel Krtous +1
The Jacobi equation for geodesic deviation describes finite size effects due to the gravitational tidal forces. In this paper we show how one can integrate the Jacobi equation in a…
