Abstract: In this article, we study the quantum dynamics of a Klein-Gordon field onde-Sitter space. We prove time evolution is not unitarily implementable. Wealso consider a Klein-Gordon field perturbed by a local potential V. In thiscase we prove that the deviation from the V=0 dynamics is unitarilyimplementable.
