A covariant and gauge invariant formulation of the cosmological "backreaction"
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 us to describe in explicitly gauge invariant form the way classical or quantum inhomogeneities affec...

| Sumario: | 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 us to describe in explicitly gauge invariant form the way classical or quantum inhomogeneities affect the average evolution of our Universe. |
