title: curvature evolution: Stephani models = beyond FLRW speaker: boud when/where: Friday 15.00 godz. 27.11.2009 @KRA.
abstract: The FLRW models assume that comoving curvature is frozen. Inflationary motivations and models try to justify flatness and homogeneity, but nevertheless assume that comoving curvature is hardwired. Wouldn't it be more realistic to consider the possibilities of curvature evolution rather than hardwiring it? The Stephani models constitute a class of exact solutions in which the curvature of spatial sections can evolve. Could they help us get a better model of the real Universe? http://arxiv.org/abs/gr-qc/9908019 Sussman http://arxiv.org/abs/astro-ph/0403534 Godlowski, Stermach, Szydlowski http://arxiv.org/abs/0902.2899 Dabrowski http://arxiv.org/abs/astro-ph/0008089 Chris A.

BTW: Feel free to look at these articles, or at least their abstracts. i've only read a little, so other people may see other interesting things that i have missed, to make a more interesting discussion.
