| dc.description.abstract | The asymptotic symmetry group (ASG) at future null infinity \((I^+)\) of four-dimensional de Sitter spacetimes is defined and shown to be given by the group of three-dimensional diffeomorphisms acting on \(I^+\). Finite charges are constructed for each choice of ASG generator together with a two-surface on \(I^+\). A conservation equation is derived relating the evolution of the charges with the radiation flux through \(I^+\). | en_US |
