Twisting algebraically special solutions in five dimensions
de, Freitas Gabriel Bernardi; Godazgar, Mahdi; Reall, Harvey Stephen (Institute of PhysicsClassical and Quantum Gravity, 2016)We determine the general form of the solutions of the five-dimensional vacuum Einstein equations with cosmological constant for which (i) the Weyl tensor is everywhere type II or more special in the null alignment ...

Uniqueness of the Kerr-de Sitter spacetime as an algebraically special solution in five dimensions
Freitas, Gabriel Bernardi de; Godazgar, Mahdi; Reall, Harvey Stephen (SpringerCommunications in Mathematical Physics, 2015-08-20)We determine the most general solution of the five-dimensional vacuum Einstein equation, allowing for a cosmological constant, with (i) a Weyl tensor that is type II or more special in the classification of Coley et al., ...
