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…
On higher dimensional Einstein spacetimes with a non-degenerate double Weyl aligned null direction
Marcello Ortaggio, Vojtěch Pravda, Alena Pravdová
We prove that higher dimensional Einstein spacetimes which possess a geodesic, non-degenerate double Weyl aligned null direction (WAND) must additionally possess a second do…
Asymptotic properties of gravitational and electromagnetic fields in higher dimensions
Marcello Ortaggio, Alena Pravdová
We summarize the fall-off of electromagnetic and gravitational fields in n>5 dimensional Ricci-flat spacetimes along an asympotically expanding non-singular geodesic null congruenc…
On the Goldberg-Sachs theorem in higher dimensions in the non-twisting case
Marcello Ortaggio, Vojtěch Pravda, Alena Pravdová
We study a generalization of the "shear-free part" of the Goldberg-Sachs theorem for Einstein spacetimes admitting a non-twisting multiple Weyl Aligned Null Direction (WAND) l in n…
