Abstract
In this talk, I will address the problem of averaging in general relativity. For this purpose, I will review the 3+1 decomposition formalism of the Einstein equation. As a simple example, I consider Buchert's approach, using conformal decomposition, I show how the averaging method adds feedback terms to the dynamical equations. I will also discuss its various generalizations and cosmol ...
