Abstract:
An earlier work that replaced the de Sitter-Schwarzschild metric for a cosmological constant Λ ≤ 0 by an effective anti-de Sitter black hole analytic at Λ = 0 is here extended to the horizon structure through its three possible roots. We replace the de Sitter-Schwarzschild metric for all possible values of Λ and the Schwarzschild radius R for the three possible available roots by either a Schwarzschild black hole whose radius depends on both R and Λ or a de Sitter space whose cosmological constant depends on both R and Λ.
