Probing non-Riemannian spacetime geometry
Dirk Puetzfeld, Yuri N. Obukhov
The equations of motion for matter in non-Riemannian spacetimes are derived via a multipole method. It is found that only test bodies with microstructure couple to the non-Riemanni…
PROCRUSTES: A computer algebra package for post-Newtonian calculations in General Relativity
Dirk Puetzfeld
We report on a package of routines for the computer algebra system Maple which supports the explicit determination of the geometric quantities, field equations, equations of motion…
Status of non-Riemannian cosmology
Dirk Puetzfeld
We provide a brief chronological guide to the literature on non-Riemannian cosmological models. Developments in this field are traced back to the early seventies and are given in t…
Testing non-standard cosmological models with supernovae
Dirk Puetzfeld, Xuelei Chen
In this work we study the magnitude-redshift relation of a non-standard cosmological model. The model under consideration was firstly investigated within a special case of metric-a…
An exact-plane fronted wave solution in metric-affine gravity
Dirk Puetzfeld
We study plane-fronted electrovacuum waves in metric-affine gravity (MAG) with cosmological constant in the triplet ansatz sector of the theory. Their field strengths are, on the g…
