A scalar field in four-dimensional deSitter spacetime (dS4) has quasinormal modes which are singular on the past horizon of the south pole and decay exponentially towards the future. These are found to lie in two complex highest-weight representations of the dS4 isometry group SO(4, 1). The Klein-Go...
