Lorentzian Condition in Holographic Cosmology

Understand

We derive a sufficient set of conditions on the Euclidean boundary theory in dS/CFT for it to predict classical, Lorentzian bulk evolution at large spatial volumes.

• Our derivation makes use of a canonical transformation to express the bulk wave function at large volume in terms of the sources of the dual partition function.
• This enables a sharper formulation of dS/CFT.
• The conditions under which the boundary theory predicts classical bulk evolution are stronger than the criteria usually employed in quantum cosmology.
