Accelerated sources in de Sitter spacetime and the insufficiency of retarded fields
Jiri Bicak, Pavel Krtous
The scalar and electromagnetic fields produced by the geodesic and uniformly accelerated discrete charges in de Sitter spacetime are constructed by employing the conformal relation…

Black Holes under External Influence
Jiri Bicak
The work on black holes immersed in external fields is reviewed in both test-field approximation and within exact solutions. In particular we pay attention to the effect of the exp…

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…
