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.
