Bulk geometric notions such as spacetime subregi ons\, extremal surfaces\, and causal structure are only sharply defined in the bulk G_N \\to 0 limit which corresponds to the boundary N \\to \\inft y limit. In this talk\, we will argue that geometric notions in the bulk e merge from the mathematical structure of the large N limit of the dual CFT \, which we have shown gives rise to the ubiquitous emergence of type III_ 1 von Neumann algebras. We explicitly construct the boundary subalgebras t hat describe bulk physics in most bulk subregions. We also comment on the relationship of our construction with quantum error correction\, subregion -subregion duality and the RT prescription.\n LOCATION:https://researchseminars.org/talk/HET/39/ END:VEVENT END:VCALENDAR
