Backreaction and the Covariant Formalism of General Relativity

Magni, Stefano

Understand

This thesis is a review of backreaction, which is a possible alternative to dark energy and modified gravity.

We describe in detail the 3+1 covariant formalism and Frobenius' theorem.
We present the averaging procedure developed by Buchert, the Buchert equations and the generalization of these equations to the case of general matter.
We then generalize to arbitrary number of spatial dimensions.
