Proposes a duality between AdS3 gravity with dS2 branes and CFT2 with non-unitary boundary conditions to realize dS holography via complex saddles and state preparation in unitary AdS/CFT.
Let the interval direction of Σ be parameterized byτ∈[−L/2, L/2] and theS 1 direction be parameterized byϕ∈[−π, π) withϕ∼ϕ+ 2π
