Point particles on the string in a three-dimensional AdS universe
Petr Lukeš, Pavel Krtouš
BTZ spacetime is a long-known locally AdS solution to the Einstein equations in 1 timelike and 2 spacelike dimensions. Its static variant is interpreted as a black hole whose mass…

Duality and -separability of Maxwell equations in Kerr-NUT-(A)dS spacetime
Valeri P. Frolov, Pavel Krtouš
We study properties of a recently proposed new ansatz for separation of variables in the Maxwell equations in four dimensional Kerr-NUT-(A)dS spacetime. We demonstrate that a dual…

Separation of variables in Maxwell equations in Plebanski-Demianski spacetime
Valeri P. Frolov, Pavel Krtouš, David Kubizňák
A new method for separating variables in Maxwell's equations in four- and higher-dimensional Kerr-(A)dS spacetimes proposed recently by Lunin is generalized to any off-shell metric…
