CLOSED CONFORMAL KILLING-YANO TENSOR AND UNIQUENESS OF GENERALIZED KERR-NUT-DE SITTER SPACETIME

摘要

We classify all spacetimes with a rank-2 closed conformal Killing-Yano tensor. They give a generalization of Kerr-NUT-de Sitter spacetime. The Einstein condition is explicitly solved. The Kerr-NUT-de Sitter spacetime is obtained as a spacetime with a non-degenerate CKY tensor.
