Abstract: A nice setup to investigate subtle aspects of how spacetime emerges from the internal degrees of freedom in holographic theories is provided by AdS3/CFT2 holography. There, quotients of AdS3 with conical singularities possess several extremal "surfaces" (curves in D=3) anchored to a fixed boundary region. The length of those curves which are extremal but non-minimal was conjectured in the past to compute some loosely defined notion of entanglement between internal degrees of freedom in the dual CFT. This quantity was dubbed "entwinement". In this talk, we will give a more precise picture of how entwinement can be defined for the setup relevant to AdS3/CFT2 holography, showing that it is indeed what the lengths of extremal but non-minimal curves are computing. Time permitting, we will also put forward some more speculative questions related to the general program of bulk reconstruction that can be discussed in the setup of quotient geometries in AdS3/CFT2.
