Abstract:
Embedding diagrams of the equatorial plane of the Kerr-de Sitter black-hole or naked-singularity spacetimes are constructed for the optical reference geometry. The embedding diagrams do not cover whole stationary parts of the Kerr-de Sitter spacetimes. Hence, limits of embeddability are discussed. The Kerr-de Sitter spacetimes are then classified according to the number of embeddable regions and the number of the turning points of the diagrams.
