Static spherically symmetric Kundt vacuum solutions of higher-derivative gravities
Breno L. Giacchini, Ivan Kolář, Vojtěch Pravda +1
We study static spherically symmetric Kundt solutions to the vacuum field equations of quadratic gravity with a cosmological constant, as well as specific models of six-derivative…
On vacuum and charged asymptotically (A)dS black holes in quadratic gravity
George Turner, Vojtěch Pravda, Alena Pravdová
In this paper, we study asymptotic properties of static spherically symmetric black holes in quadratic gravity with a cosmological constant . We find that for sufficiently large…
Almost universal spacetimes in higher-order gravity theories
Martin Kuchynka, Tomáš Málek, Vojtěch Pravda +1
We study almost universal spacetimes - spacetimes for which the field equations of any generalized gravity with the Lagrangian constructed from the metric, the Riemann tensor and i…
Universal spacetimes in four dimensions
Sigbjørn Hervik, Vojtěch Pravda, Alena Pravdová
Universal spacetimes are exact solutions to all higher-order theories of gravity. We study these spacetimes in four dimensions and provide necessary and sufficient conditions for u…
Curvature invariants in algebraically special spacetimes
V. Pravda, J. Bicak
It is well known that all curvature invariants of the order zero vanish for type-III and type-N vacuum spacetimes. We briefly summarize properties of higher order curvature invaria…
Curvature invariants in type-III spacetimes
V. Pravda
The results of paper [1] are generalized for vacuum type-III solutions with, in general, a non-vanishing cosmological constant Lambda. It is shown that all curvature invariants con…
