4 v 1 3 0 Se p 19 97 ( Anti-) Evaporation of Schwarzschild-de Sitter Black Holes

We study the quantum evolution of black holes immersed in a de Sitter background space. For black holes whose size is comparable to that of the cosmological horizon, this process differs significantly from the evaporation of asymptotically flat black holes. Our model includes the one-loop effective action in the s-wave and large N approximation. Black holes… CONTINUE READING
