Robinson-Trautman spacetimes with an electromagnetic field in higher dimensions
Marcello Ortaggio, Jiri Podolsky, Martin Zofka
We investigate higher dimensional Robinson-Trautman spacetimes with an electromagnetic field aligned with the hypersurface orthogonal, non-shearing, expanding geodesic null congrue…
Type D Einstein spacetimes in higher dimensions
Vojtech Pravda, Alena Pravdova, Marcello Ortaggio
We show that all static spacetimes in higher dimensions are of Weyl types G, I_i, D or O. This applies also to stationary spacetimes if additional conditions are fulfilled, as for…
Ricci identities in higher dimensions
Marcello Ortaggio, Vojtech Pravda, Alena Pravdova
We explore connections between geometrical properties of null congruences and the algebraic structure of the Weyl tensor in n>4 spacetime dimensions. First, we present the full set…
Higher dimensional spacetimes with a geodesic, shearfree, twistfree and expanding null congruence
Marcello Ortaggio
We present the complete family of higher dimensional spacetimes that admit a geodesic, shearfree, twistfree and expanding null congruence, thus extending the well-known D=4 class o…
