AdS gravastar and bulk-cone singularities

Journal of High Energy Physics
The horizon of black hole is surrounded by the photon sphere and an outside observer cannot easily examine the geometry inside the photon sphere. In this note, we propose a way to investigate the region from dual conformal field theory by making use of ...

Topological modular forms and conformal nets

, 2011
We describe the role conformal nets, a mathematical model for conformal field theory, could play in a geometric definition of the generalized cohomology theory TMF of topological modular forms.

Stanilov-Tsankov-Videv Theory

Symmetry, Integrability and Geometry: Methods and Applications, 2007
We survey some recent results concerning Stanilov-Tsankov-Videv theory, conformal Osserman geometry, and Walker geometry which relate algebraic properties of the curvature operator to the underlying geometry of the manifold.

Geometrothermodynamics as a singular conformal thermodynamic geometry

Physics Letters B, 2019
In this letter, we first redefine our formalism of the thermodynamic geometry introduced in [1,2] by changing coordinates of the thermodynamic space by means of Jacobian matrices.

Special Types of Locally Conformal Closed G₂-Structures

Axioms, 2018
Motivated by known results in locally conformal symplectic geometry, we study different classes of G 2 -structures defined by a locally conformal closed 3-form.

Breaking away from the near horizon of extreme Kerr

SciPost Physics, 2020
We study gravitational perturbations around the near horizon geometry of the (near) extreme Kerr black hole. By considering a consistent truncation for the metric fluctuations, we obtain a solution to the linearized Einstein equations. The dynamics is

AdS gravastar and its signatures from dual conformal field theory

Physical Review Research
Quantum gravity effects are expected to resolve the black hole singularity and the effects may deform the region near but outside the horizon. Applying AdS/CFT correspondence, we see their signatures from the viewpoint of dual conformal field theory.
