"Nonextremal black holes, subtracted geometry and holography"
 
 Slideshow (PDF)
ABSTRACT:

We review the thermodynamic properties of general asymptotically flat black holes in four dimensions, suggestive of a dual conformal field theory interpretation. We introduce the so-called subtracted geometry as an ``asymptotically conical box'' of non-extremal black holes where the conformal symmetry becomes manifest. Employing holographic renormalization techniques in a variational problem in terms of equivalence classes of boundary data under the local asymptotic symmetries of the theory, we derive the conserved charges and the first law of thermodynamics for the subtracted geometry. We also formulate a holographic dictionary for this geometry in terms of a two-dimensional Einstein-Maxwell-Dilaton model.
