Topological classes of black holes in de-Sitter spacetime
Yongbin Du, Xiangdong Zhang
In this paper, we investigate the topological number of de-Sitter black hole solutions with different charges and rotational parameters. By using generalized free energ…

Topological classes of BTZ black holes
Yongbin Du, Xiangdong Zhang
In the recent paper [Phys. Rev. Lett. 129, 191101 (2022)], the black holes were viewed as topological thermodynamic defects by using the generalized off-shell free energy. Their wo…
