Kinematic Space and Wormholes

Understand

The kinematic space could play a key role in constructing the bulk geometry from dual CFT.

• In this paper, we study the kinematic space from geometric points of view, without resorting to differential entropy.
• We find that the kinematic space could be intrinsically defined in the embedding space.
• For each oriented geodesic in the Poincar\'e disk, there is a corresponding point in the kinematic space.
