文摘In a previous publication,we claimed that a black hole can be considered as a topological insulator.A direct consequence of this claim is that their symmetries should be related.In this paper,we give a representation of the near-horizon symmetry algebra of the BTZ black hole using the W1+∞symmetry algebra of the topological insulator in three-dimensional spacetime.Based on the W1+∞algebra,we count the number of the microstates of the BTZ black holes and obtain the Bekenstein-Hawking entropy.
