Abstract
We briefly recall the problem of defining conserved quantities such as energy in general relativity, and the solution given by introducing a symmetric background. We apply the general formalism to perturbed Rob ertson-Walker spacetimes with de Sitter geometry as background. We rel ate the obtained conserved quantities to Traschen's integral constrain ts and mention a few applications in cosmology.
