本文利用欧几里德引力导出了黑洞微观态密度的一个简单公式,这些微观态在任何有限规范群的每个不可约表示中变换。由于每个表示都以非零密度出现,这为有限规范场的完整性假设提供了新的证明。受此一般性的启发,我们进一步提出,该公式在高能时适用于任何具有有限群整体对称性的量子场论,并给出了这一猜想的一些证据。
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.
