title: curvature evolution: Stephani models = beyond FLRW
when/where: Friday 15.00 godz. 27.11.2009 @KRA.
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?

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.
