Optimal covariant fitting to a Robertson-Walker metric and smallness of backreaction
Dieter Gromes
We define a class of "optimal" coordinate systems by requiring that the deviation from an exact Robertson-Walker metric is "as small as possible" within a given four dimensional vo…

Lowest order covariant averaging of a perturbed metric and of the Einstein tensor II
Dieter Gromes
We generalize and simplify an earlier approach. In three dimensions we present the most general averaging formula in lowest order which respects the requirements of covariance. It…

Lowest order covariant averaging of a perturbed metric and of the Einstein tensor
Dieter Gromes
We present an explicit averaging formula in lowest order. Besides an arbitrary smearing function it contains two integrals of this function. This is necessary in order to achieve c…
