relating (super-)gravity to (super-)Yang-Mills theory:
Seiberg duality (swapping NS5-branes)
What is called flat space holography is a, somewhat more hypothetical, generalization of the holographic principle in the form of the AdS-CFT correspondence, that should be applicable not to bulks that are asymptotically anti de Sitter but to bulks that are asymptotically Minkowskian.
Notice here that the far horizon geometry of all BPS branes is a flat orbifold spacetime (see here) and that “far” is Planck scale for single branes (“cone branes”), hence in the large 1/N limit (opposite to the large N limit in which the AdS-CFT correspondence applies).
In one more well-developed version of flat space holography, scattering amplitudes in asymptotically flat spacetimes are related to conformal field theories on celestial spheres in two dimensions lower – “celestial amplitudes”. This goes back to an observation in de Boer & Solodukhin 2003.
