general mechanisms
electric-magnetic duality, Montonen-Olive duality, geometric Langlands duality
string-fivebrane duality
string-QFT duality
QFT-QFT duality:
effective QFT incarnations of open/closed string duality,
relating (super-)gravity to (super-)Yang-Mills theory:
Seiberg duality (swapping NS5-branes)
transfinite arithmetic, cardinal arithmetic, ordinal arithmetic
prime field, p-adic integer, p-adic rational number, p-adic complex number
arithmetic geometry, function field analogy
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 $PGL(2,\mathbb{Q}_p)$:

This may be regarded (at some finite depth truncation) as a tensor network state:
graphics from Sati-Schreiber 19c
(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.)
Suggestion to identify the Bruhat-Tits tree $T_p$ with anti de Sitter spacetime in the p-adic AdS/CFT correspondence:
