DESCRIPTION:The 4D rotating black hole described by the Kerr g
eometry\npossesses many of what was called by Chan
drasekhar "miraculous" properties.\nMost of them c
an be related to the existence of a fundamental hi
dden\nsymmetry called the principal conformal Kill
ing-Yano (PCKY) tensor. In my\ntalk I shall demons
trate that\, in this context\, four dimensions are
not\nexceptional and that the (spherical horizon
topology) higher-dimensional\nrotating black holes
are very similar to their four-dimensional cousin
s.\nNamely\, I shall present the most general spac
etime admitting the PCKY tensor\nand show that is
possesses the following properties: 1) It is of th
e\nalgebraic type~D of the higher-dimensional alge
braic classification. 2) It\nallows a separation o
f variables for the Hamilton--Jacobi\, Klein--Gord
on\,\nDirac\, and stationary string equations. 3)
The geodesic motion in such a\nspacetime is comple
tely integrable. The problem of finding\nparallel-
propagated frames reduces to the set of the first
order ordinary\ndifferential equations. 4) When th
e Einstein equations with the cosmological\nconsta
nt are imposed the metric becomes the Kerr-NUT-(A)
dS spacetime.
