BACKREACTION IN RELATIVISTIC COSMOLOGY
(http://www.worldscientific.com/doi/pdfplus/10.1142/S0218271813300048, 201303)We introduce the concept of backreaction in relativistic cosmological modeling. Roughly speaking, this can be thought of as the difference between the largescale behavior of an inhomogeneous cosmological solution of ...

Constraints on the Variation of G from Primordial Nucleosynthesis
We study here the effect of a varying G on the evolution of the early Universe and, in particular, on primordial nucleosynthesis. This variation of G is modelled using the BransDicke theory as well as a more general class ... 
Cosmologies with Energy Exchange
We provide a simple mathematical description of the exchange of energy between two fluids in an expanding Friedmann universe with zero spatial curvature. The evolution can be reduced to a single nonlinear differential ... 
Cosmology Without Averaging
We construct cosmological models consisting of large numbers of identical, regularly spaced masses. These models do not rely on any averaging procedures, or on the existence of a global FriedmannRobertsonWalker (FRW) ...
