A linearized mass loss law: with or without a positive cosmological constant

Bondi's celebrated "mass-loss" formula measures the rate of change of energy carried away from an isolated system (in asymptotically flat space-time) by gravitational radiation. In this talk, we discuss the "mass-loss" formula for linearized gravitational fields in covariant phase-space formalism. We also generalize this idea in the de Sitter setting.
