Born-Infeld-de Sitter gravity: Cold, ultracold and Nariai black holes

Understand

In this paper, we have presented interesting properties of the static charged Born-Infeld-de Sitter black hole.

• They can have time-like as well as space-like singularities depending on the parameters of the theory.
• The degenerate black holes lead to cold, ultra cold and Nariai black holes.
• The geometry of such black holes are discussed.
