Topological classes of black holes in de-Sitter spacetime
Abstract In this paper, we investigate the topological number of de-Sitter black hole solutions with different charges (q) and rotational (a) parameters. By using generalized free energy and Duan’s $$\phi $$ ϕ -mapping topological current theory, we find that the topological numbers of black holes c...
