TL;DR
These universal results may provide a "looking glass" for probing the microscopics of general black holes if the latter is also quantized, and depend only on the quantized charges, quantized angular momenta and the cosmological constant.
Abstract
We present explicit results for the product of all horizon areas for general rotating multi-charge black holes, both in asymptotically flat and asymptotically anti-de Sitter spacetimes in four and higher dimensions. The expressions are universal, and depend only on the quantized charges, quantized angular momenta and the cosmological constant. If the latter is also quantized these universal results may provide a "looking glass" for probing the microscopics of general black holes.
