Complex Kerr-Newman geometry and black-hole thermodynamics
Abstract
We establish that in the functional-integral expression for the grand partition function, the thermodynamic properties of a charged, rotating black hole are derived from a complex geometry. The corresponding real ``thermodynamical'' action is constructed explicitly.
