Conical singularity in spacetimes with NUT is observer-dependent
Ivan Kolář, Pavel Krtouš, Maciej Ossowski
We discuss the issue of defining and measuring conical deficits (conicity) in spacetimes with the torsion singularity such as the Misner string in Taub--NUT spacetime. We propose a…
Conformal Einstein equation and symplectic flux with a positive cosmological constant
Sk Jahanur Hoque, Pavel Krtouš, Carlos Peón-Nieto
We analyze the conformal Einstein equation with a positive cosmological constant to extract fall-off conditions of the gravitational fields. The fall-off conditions are consistent…
On a lower-dimensional Killing vector origin of irreducible Killing tensors
Finnian Gray, Gloria Odak, Pavel Krtouš +1
Considering a spacetime foliated by co-dimension-2 hypersurfaces, we find the conditions under which lower-dimensional symmetries of a base space can be lifted up to irreducible Ki…
