Idea

A version of the AdS/CFT correspondence (specifically: AdS3/CFT2 duality) for p-adic physics, obtained by passing on the conformal field theory-side from the complex geometry, hence (via GAGA)algebraic geometry of 2d CFT to arithmetic geometry over p-adic numbers, and on the string theory-side to p-adic string theory (?)

Here the arithmetic geometry-version of the bulk AdS spacetime is identified with the Bruhat-Tits tree for the projective general linear group PGL(2, p)PGL(2,\mathbb{Q}_p):

This may be regarded (at some finite depth truncation) as a tensor network state:

(As in HMSS 16, HLM 19. But maybe one wants the Poincaré-dual networks, instead, as in HMPS 18?)

There is the suggestion that BTZ black holes are encoded by networks that look like Bruhat-Tits trees towards the boundaries and like matrix product states towards the interior:

(As in ESZ 19.)
