Abstract
Using our recent proposal for defining gauge invariant averages we give a general-covariant formulation of the so-called cosmological "backreaction". Our effective covariant equations allow to describe in an explicitly gauge invariant form the way classical or quantum inhomogeneities affect the average evolution of our Universe.File in questo prodotto:
