Remark About dS / CFT Correspondence

In this paper we will study some aspects of dS/CFT correspondence. We will focus on the relation between Witten's non-standard de Sitter inner product and correlators in the holographic dual conformal field theory. We will argue that from the definition of Witten's inner product and conjecture that the Hilbert space of initial states of massive scalar field on I − in de Sitter space corresponds to the Hilbert space of states of Euclidean CFT on I − , we can obtain CFT correlators in any vacuum state.
