Linearized gravitational waves near space-like and null infinity
Florian Beyer, Georgios Doulis, Jörg Frauendiener +1
Linear perturbations on Minkowski space are used to probe numerically the remote region of an asymptotically flat space-time close to spatial infinity. The study is undertaken with…
Numerical space-times near space-like and null infinity. The spin-2 system on Minkowski space
Florian Beyer, Georgios Doulis, Jörg Frauendiener +1
In this paper we demonstrate for the first time that it is possible to solve numerically the Cauchy problem for the linearisation of the general conformal field equations near spac…
The cosmic no-hair conjecture: A study of the Nariai solutions
Florian Beyer
In this talk, we investigate the cosmic no-hair conjecture for perturbed Nariai solutions within the class of Gowdy symmetric solutions of Einstein's field equations in vacuum with…
Investigations of solutions of Einstein's field equations close to lambda-Taub-NUT
Florian Beyer
We present investigations of a class of solutions of Einstein's field equations close to the family of lambda-Taub-NUT spacetimes. The studies are done using a numerical code intro…
A spectral solver for evolution problems with spatial S3-topology
Florian Beyer
We introduce a single patch collocation method in order to compute solutions of initial value problems of partial differential equations whose spatial domains are 3-spheres. Beside…
Asymptotics and singularities in cosmological models with positive cosmological constant
Florian Beyer
This thesis is concerned with global properties of those cosmological solutions of Einstein's field equations which obey accelerated expansion into the future driven by a non-vanis…
