Popis: In this paper we use Euclidean gravity to derive a simple formula for the density of black hole microstates which transform in each irreducible representation of any finite gauge group. Since each representation appears with nonzero density, this gives a new proof of the completeness hypothesis for finite gauge fields. Inspired by the generality of the argument we further propose that the formula applies at high energy in any quantum field theory with a finite-group global symmetry, and give some evidence for this conjecture.
Comment: v3: references added and some minor additions v2: major revision due to several people pointing out an error in the discussion of the weak gravity conjecture. Now only presents the second main result of v1, a formula for the density of black hole microstates in each representation of a finite gauge group and an associated conjecture for general QFTs, for which some more evidence is given
