In three spacetime dimensions, general relativity becomes a topological field theory, whose dynamics can be largely described holographically by a two-dimensional conformal field theory at the ``boundary'' of spacetime. I review what is known about this reduction--mainly within the context of pure (2+1)-dimensional gravity--and discuss its implications for our understanding of the statistical mechanics and quantum mechanics of black holes.

  1. Enhanced Conformal $BMS_3$ Symmetries

    hep-th 2024-12 conditional novelty 7.0 of 10

    A boundary-condition analysis of extended conformal gravity in 3D yields a new nonlinear W(2,2,2,2,1,1,1) asymptotic symmetry algebra whose central charges are fixed by the Virasoro central charge.

  2. On Integrable Structures on Non-compact Boundaries in Three-Dimensional Gravity

    hep-th 2026-07 conditional novelty 6.0 of 10

    In the diagonal (Cartan) sector of AdS3 gravity, the radial flow of the quasi-local stress tensor satisfies an exact T Tbar-like equation, while the boundary time evolution forms an integrable bi-Hamiltonian hierarchy.

  3. Spectral Bifurcations in Quasinormal Modes of Regular BTZ Black Holes

    gr-qc 2026-03 conditional novelty 6.0 of 10

    For regular BTZ black holes from an infinite Lovelock tower, scalar quasinormal modes bifurcate from complex BTZ branches into purely imaginary branches as the regularization length ℓ grows, producing mode switching a...

  4. Strings near BTZ black holes: A Carrollian Chronicle

    hep-th 2025-10 unverdicted novelty 6.0 of 10

    The paper classifies families of closed bosonic string solutions in the near-horizon non-extremal BTZ spacetime and identifies novel features via string-Carroll expansion.

  5. Holonomies and Boundary Symmetries in the Discrete Warped Chern-Simons Gravity

    hep-th 2026-06 unverdicted novelty 5.0 of 10

    The paper derives a discrete entropy formula for warped black holes directly from SL(2,R) x U(1) boundary monodromy invariants that recovers the continuum warped thermodynamics in the large-lattice limit.

  6. Optimal Control Theory of the (2+1)-Dimensional BTZ Black Hole

    gr-qc 2025-12 conditional novelty 5.0 of 10

    Geodesics of the Weinhold and Ruppeiner thermodynamic metrics are computed for the BTZ black hole and interpreted as optimal evaporation/accretion protocols.

  7. Effective Metric Description of 2+1 Dimensional Quantum Black Holes

    gr-qc 2024-12 conditional novelty 5.0 of 10

    A framework for writing quantum corrections to the rotating BTZ black hole in coordinate-invariant form, with horizon regularity constraints and a general temperature formula.

  8. Lecture notes on strings in AdS$_3$ from the worldsheet and the AdS$_3$/CFT$_2$ duality

    hep-th 2026-01 unverdicted novelty 2.0 of 10

    Lecture notes deliver a self-contained pedagogical overview of worldsheet strings in AdS3 with NSNS flux, summarizing 25 years of results with emphasis on spectrally flowed correlation functions.
