Scientific paper

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