We study holographic entanglement entropy in dS/CFT and introduce timelike entanglement
entropy in CFTs. Both of them take complex values in general and are related with each …

A bstract We define a new complex-valued measure of information called the timelike
entanglement entropy (EE) which in the boundary theory can be viewed as a Wick rotation …

We propose a codimension-two holography between a gravitational theory on ad+ 1
dimensional wedge spacetime and ad-1 dimensional CFT which lives on the corner of the …

We refine previous investigations on de Sitter space and extremal surfaces anchored at the
future boundary I+. Since such surfaces do not return, they require extra data or boundary …

Bayes' rule, P (B| A) P (A)= P (A| B) P (B), is one of the simplest yet most profound,
ubiquitous, and far-reaching results of classical probability theory, with applications in any …

A bstract We present a class of dS/CFT correspondence between two-dimensional CFTs
and three-dimensional de Sitter spaces. We argue that such a CFT includes an SU (2) WZW …

In this Letter, we propose a holographic duality for classical gravity on a three-dimensional
de Sitter space. We first show that a pair of SU (2) Chern-Simons gauge theories reproduces …

A bstract A long-standing and intriguing question is: does the holographic principle apply to
cosmologies like de Sitter spacetime? In this work, we consider a half dS spacetime wherein …

A bstract In this paper, we study the dynamics of end-of-the-world (EOW) branes in AdS with
scalar fields localized on the branes as a new class of gravity duals of CFTs on manifolds …

We develop further the investigations by Narayan [de Sitter space, extremal surfaces, and
time entanglement, Phys. Rev. D 107, 126004 (2023) PRVDAQ 2470-0010 …
