  "abstract": "In this work we consider a particular codimension-one region of a holographic spacetime which we call the entanglement wedge polygon (EWP). For a pure state and a partition of the boundary into a number of regions Ai the EWP is defined as the region with maximal volume external to all the individual homology regions $$ {r}_{A_i} $$ which consist of the intersection of the entanglement wedge EW(Ai) with the time slice. In three dimensions, when the EWP has constant curvature as in vacuum AdS3 and BTZ spacetime, its volume is topological as a direct consequence of the Gauss-Bonnet theorem. The topological nature is lost in the time-dependent covariant case and in the presence of an end-of-the-world brane. In higher dimensions we make progress by considering a number of concrete examples including vacuum, black brane, and soliton solutions of AdSd+1 as well as spacetime geometries with end-of-the-world branes dual to boundary conformal field theories. We provide a suitable generalization to mixed states and comment on possible connections between the EWP and measures of multi-partite entanglement.",
