Description
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.
