Some Properties of Kerr Geometry with a Repulsive Cosmological Constant |
Abstract _ |
We summarize general properties of the Kerr-de Sitter geometry (i.e., with a repulsive cosmological constant). We find all existing horizons, ergospheres and main representatives of stationary frames. Then we focus on special class of stationary frames, namely, freely falling observers which could lead to measurable effects if even a small positive cosmological constant is included. |
