"CFT Dual of dS3 and Pseudo Entropy"
We propose a holographic duality for gravity on a three-
dimensional de Sitter space. This is essentially given by a k=-2 limit
of SU(2) WZW model. We show that this proposal reproduces the expected
free energy in de Sitter gravity. We also analyze the geodesic length in
the three dimensional de Sitter spacetime and argue that it is
interpreted as holographic pseudo entropy. We will also discuss a time-
like entanglement entropy in AdS/CFT which shares a similar property in
terms of pseudo entropy.
