     title: curvature evolution: Stephani models = beyond FLRW
     speaker: boud
     when/where: Friday 15.00 godz. 22.01.2010 @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?

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.
