Asymptotic expansions close to the singularity in Gowdy spacetimes
Hans Ringstrom
We consider Gowdy spacetimes under the assumption that the spatial hypersurfaces are diffeomorphic to the torus. The relevant equations are then wave map equations with the hyperbo…

Future asymptotic expansions of Bianchi VIII vacuum metrics
Hans Ringstrom
Bianchi VIII vacuum solutions to Einstein's equations are causally geodesically complete to the future, given an appropriate time orientation, and the objective of this article is…
