Description
Our talk will start with a (hopefully) pedagogical introduction to the
topic of asymptotically de Sitter spacetimes. Afterward, we will
construct 'conserved' charges a'la Wald and Zoupas at a conformal
infinity and prove their uniqueness under a natural set of
assumptions. We will finish with a small comment on how to distinguish
the de Sitter group within a group of all asymptotic symmetries.
