The evolution of an inhomogeneous universe composed entirely of matter is followed from an early, nearly uniform state until the time when the inhomogeneities have begun to grow large. The particular distribution of matter studied in this article is chosen to have a periodic variation in only one of the directions, which is simple enough to allow the behavior of the metric to be solved analytically, well beyond a linear approximation based on the initial smallness of the fluctuation. This… Expand
A gradient expansion for cosmological backreaction
We address the issue of cosmological backreaction from non-linear structure formation by constructing an approximation for the time evolved metric of a dust dominated universe based on a gradientExpand
Back reaction from walls
We study the distance-redshift relation in a universe filled with 'walls' of pressure-less dust separated by under dense regions. We show that as long as the density contrast of the walls is small,Expand
Theoretical and observational aspects of relativistic cosmology
Durant ma these j'ai travaille sur des aspects theoriques et observationnels de la cosmologie relativiste. D'un point de vue theorique, j'ai considere deux possibles solutions au probleme deExpand
