Antievaporation of Schwarzschildde Sitter black holes in F(R) gravity
Abstract
We studied the antievaporation of a degenerate Schwarzschildde Sitter black hole (socalled Nariai spacetime) in modified F(R) gravity. We analyze the perturbations in the Nariai black hole and find that antievaporation may occur in F(R) gravity even at a classical level. For several powerlaw F(R) gravities which may describe the inflation and/or dark energy eras, we presented the theory parameter bounds for the occurrence of antievaporation and conjectured creation of an infinite number of horizons.
