Marginally trapped surfaces in Minkowski 4-space invariant under a rotation subgroup of the Lorentz group
Stefan Haesen, Miguel Ortega
A local classification of spacelike surfaces in Minkowski 4-space, which are invariant under spacelike rotations, and with mean curvature vector either vanishing or lightlike, is o…
Boost invariant marginally trapped surfaces in Minkowski 4-space
Stefan Haesen, Miguel Ortega
The extremal and partly marginally trapped surfaces in Minkowski 4-space, which are invariant under the group of boost isometries, are classified. Moreover, it is shown that there…
A new method to construct spacetimes with a spacelike circle action
Stefan Haesen, Francisco Palomo, Alfonso Romero
A new general procedure to construct realistic spacetimes is introduced. It is based on the null congruence on a time-oriented Lorentzian manifold associated to a certain timelike…
Ideally embedded space-times
Stefan Haesen, Leopold Verstraelen
Due to the growing interest in embeddings of space-time in higher-dimensional spaces we consider a specific type of embedding. After proving an inequality between intrinsically def…
