On the canonical energy of weak gravitational fields with a cosmological constant $$\varLambda \in \mathbb {R}$$ Λ ∈ R
Abstract We analyse the canonical energy of vacuum linearised gravitational fields on light cones on a de Sitter, Minkowski, and Anti de Sitter backgrounds in Bondi gauge. We derive the associated asymptotic symmetries. When $$\varLambda >0$$ Λ > 0 the energy diverges, but a renormalised formu...
