Zusammenfassung:
We study conformal symmetries on the horizon of a general stationary and
axisymmetric black hole. We find that there exist physically reasonable
boundary conditions that uniquely determine a set of symmetry generators, which
form one copy of the Virasoro algebra. For extremal black holes, Cardy's
formula reproduces exactly the Bekenstein-Hawking entropy.
