Symmetry-based approaches to the black hole entropy problem have a number of attractive features; in particular, they are very general and do not depend on the details of the quantization method. However, we point out that, of the two available approaches, one faces conceptual problems (also emphasized by others), while the second contains certain technical flaws. We correct these errors and, within the new, improved scheme, calculate the entropy of three-dimensional black holes. We find that… Expand
Horizons, Constraints, and Black Hole Entropy
Abstract Black hole entropy appears to be “universal”—many independent calculations, involving models with very different microscopic degrees of freedom, all yield the same density of states. IExpand
Symmetries, horizons, and black hole entropy
Black holes behave as thermodynamic systems, and a central task of any quantum theory of gravity is to explain these thermal properties. A statistical mechanical description of black hole entropyExpand
Black Hole Entropy and the Problem of Universality
To derive black hole thermodynamics in any quantum theory of gravity, one must introduce constraints that ensure that a black hole is actually present. For a large class of black holes, theExpand
Black hole entropy, universality, and horizon constraints
To ask a question about a black hole in quantum gravity, one must restrict initial or boundary data to ensure that a black hole is actually present. For two-dimensional dilaton gravity, and probablyExpand
Black-hole entropy and thermodynamics from symmetries
Given a boundary of spacetime preserved by a Diff(S1) sub-algebra, we propose a systematic method to compute the zero mode and the central extension of the associated Virasoro algebra of charges.Expand
Two Dimensional Conformal Symmetry and the Microscopic Interpretation of Black Hole Entropy
In this thesis the research work, done by the author in the three years of his Ph.D. study, will be exposed. The role of two dimensional conformal field theories will be discussed. DifferentExpand
The Hamiltonian dynamics of bounded spacetime and black hole entropy: the canonical method
Abstract From first principles, I present a concrete realization of Carlip's idea on black hole entropy from conformal field theory on the horizon in any dimension. The new formulation is free of theExpand
Can one understand black hole entropy without knowing much about quantum gravity
It is a common belief now that the explanation of the microscopic origin of the Bekenstein-Hawking entropy of black holes should be available in quantum gravity theory, whatever this theory willExpand
Black hole entropy and the problem of universality
A key test of any quantum theory of gravity is its ability to reproduce the known thermodynamic properties of black holes. A statistical mechanical description of the Bekenstein-Hawking entropy onceExpand
Symmetries at stationary Killing horizons
It has often been suggested (especially by S. Carlip) that spacetime symmetries in the neighborhood of a black hole horizon may be relevant to a statistical understanding of the Bekenstein–HawkingExpand


Black Hole Entropy from Conformal Field Theory in Any Dimension
Restricted to a black hole horizon, the ``gauge'' algebra of surface deformations in general relativity contains a Virasoro subalgebra with a calculable central charge. The fields in any quantumExpand
Quantum geometry of isolated horizons and black hole entropy
Using the earlier developed classical Hamiltonian framework as the point of departure, we carry out a non-perturbative quantization of the sector of general relativity, coupled to matter, admittingExpand
Entropy from conformal field theory at Killing horizons
On a manifold with a boundary, the constraint algebra of general relativity may acquire a central extension, which can be computed using covariant phase space techniques. When the boundary is aExpand
Black hole entropy from near-horizon microstates
Black holes whose near-horizon geometries are locally, but not necessarily globally, AdS3 (three-dimensional anti-de Sitter space) are considered. Using the fact that quantum gravity on AdS3 is aExpand
Geometry of the 2+1 black hole.
The geometry of the spinning black holes of standard Einstein theory in 2+1 dimensions, with a negative cosmological constant, and without couplings to matter, is analyzed in detail. It is shown thatExpand
Quantum geometry and black hole entropy
A ``black hole sector'' of nonperturbative canonical quantum gravity is introduced. The quantum black hole degrees of freedom are shown to be described by a Chern-Simons field theory on the horizon.Expand
Isolated horizons: Hamiltonian evolution and the first law
A framework was recently introduced to generalize black hole mechanics by replacing stationary event horizons with isolated horizons. That framework is significantly extended. The extension isExpand
Generic isolated horizons and their applications
The framework provides new tools to extract physics from strong field geometry and leads to a generalization of the zeroth and first laws of black hole mechanics and sheds new light on the "origin of the first law". Expand
Asymptotically anti-de Sitter spaces
Asymptotically anti-de Sitter spaces are defined by boundary conditions on the gravitational field which obey the following criteria: (i) they are O(3, 2) invariant; (ii) they make the O(3, 2)Expand
Role of surface integrals in the Hamiltonian formulation of general relativity
Abstract It is shown that if the phase space of general relativity is defined so as to contain the trajectories representing solutions of the equations of motion then, for asymptotically flat spaces,Expand
