Exact inhomogeneous scalar field universes

Classical and Quantum Gravity, 1993
We present a family of exact solutions to the Einstein field equations which describe inhomogeneous generalizations of spatially flat FRW cosmologies. The self-interacting scalar field with an exponential potential of the form V approximately ek phi serves as a source for the expansion. We show that these inhomogeneous models never inflate and briefly

Averaging the inhomogeneous universe

2006
We re-formulate and examine T. Buchert’s recent averaging scheme for scalars in cosmological applications of general relativity. The equation thus obtained can be used to describe the averaged quantities of an arbitrary inhomogeneous co-moving region and show the importance of back-reaction. We also study the use of information theory in this averaging

Averaging of a locally inhomogeneous realistic universe

Physical Review D, 1996
We present an averaging scheme in general relativity which allows us to study the effect of local inhomogeneity on the global behavior of the universe. The scheme uses 3+1 splitting of spacetime and introduces Isaacson averaging on the spatial hypersurface to get the averaged geometry.
