Averaging in LRS class II spacetimes
Petr Kaspar, Otakar Svitek
We generalize Buchert's averaged equations [Gen. Rel. Grav. 32, 105 (2000); Gen. Rel. Grav. 33, 1381 (2001)] to LRS class II dust model in the sense that all Einstein equations are…

Modelling Inhomogeneity in Szekeres Spacetime
David Vrba, Otakar Svitek
We study the behaviour of the density contrast in quasi-spherical Szekeres spacetime and derive its analytical behaviour as a function of and . We set up the inhomogeneity u…

Averaging in cosmology based on Cartan scalars
Petr Kaspar, Otakar Svitek
We present a new approach for averaging in general relativity and cosmology. After a short review of the theory originally taken from the equivalence problem, we consider two ways…
