Holography from number theory: Emergent holographic AdS${}_2$ space-time from exact BPS black hole microstate counting

Gabriel Lopes Cardoso, Suresh Nampuri

In this note, starting from the exact counting formulae for 4D BPS black hole degeneracies in the cases of 1/2 BPS $\mathcal{N}=4$ and 1/8 BPS $\mathcal{N}=8$ solutions, expressed…
