Description
We consider rules for modifying holographic tensor networks proposed in two independent contexts: by Akers et al. (CO) to incorporate observers in holographic maps, and by Kaya-Rath-Ritchie (KRR) to derive the Bousso-Penington generalized entanglement wedge proposal. Interestingly, these two sets of tensor network rules are exactly equivalent, KRR = CO. This suggests a more general connection between these Abdalla-Antonini-Iliesiu-Levine (AAIL) inspired observer rules and generalized entanglement wedges. To pursue this connection, we first use KRR’s analogous rules for the gravitational path integral (based on fixed geometry states) to generalize AAIL’s path integral rules to include observers occupying a bulk subregion. Additionally, we leverage the connection in the opposite direction by using the AAIL rules to derive the Bousso-Penington proposal for pointlike bulk regions in JT gravity.
