Covariant conserved currents for scalar-tensor Horndeski theory
Josef Schmidt, Jiří Bičák
The scalar-tensor theories have become popular recently in particular in connection with attempts to explain present accelerated expansion of the universe, but they have been consi…
Black Holes and Magnetic Fields
Filip Hejda, Jiří Bičák
We briefly summarise the basic properties of spacetimes representing rotating, charged black holes in strong axisymmetric magnetic fields. We concentrate on extremal cases, for whi…
Variations on spacetimes with boost-rotation symmetry
Jiří Bičák, David Kofroň
Some new results on the boost-rotation symmetric spacetimes representing pairs of rotating charged objects accelerated in opposite directions are summarized. A particular attention…
Monopole and dipole layers in curved spacetimes: formalism and examples
Norman Gürlebeck, Jiří Bičák, Antonio C. Gutiérrez-Piñeres
The discontinuities of electromagnetic test fields generated by general layers of electric and magnetic monopoles and dipoles are investigated in general curved spacetimes. The equ…
Spherical Gravitating Condensers in General Relativity
Jiří Bičák, Norman Gürlebeck
By a spherical gravitating condenser we mean two concentric charged shells made of perfect fluids restricted by the condition that the electric field is nonvanishing only between t…
