Gowdy phenomenology in scale-invariant variables
Lars Andersson, Henk van Elst, Claes Uggla
The dynamics of Gowdy vacuum spacetimes is considered in terms of Hubble-normalized scale-invariant variables, using the timelike area temporal gauge. The resulting state space for…
Asymptotic isotropization in inhomogeneous cosmology
Woei Chet Lim, Henk van Elst, Claes Uggla +1
In this paper we investigate asymptotic isotropization. We derive the asymptotic dynamics of spatially inhomogeneous cosmological models with a perfect fluid matter source and a po…
Spherically symmetric relativistic stellar structures
J. Mark Heinzle, N. Rohr, C. Uggla
We investigate relativistic spherically symmetric static perfect fluid models in the framework of the theory of dynamical systems. The field equations are recast into a regular dyn…
The past attractor in inhomogeneous cosmology
Claes Uggla, Henk van Elst, John Wainwright +1
We present a general framework for analyzing spatially inhomogeneous cosmological dynamics. It employs Hubble-normalized scale-invariant variables which are defined within the orth…
