Three Dimensional near - Horizon Metrics

چکیده
We investigate which three dimensional near-horizon metrics gNH admit a compatible 1-form X such that (X, [gNH ]) defines an Einstein-Weyl structure. We find explicit examples and see that some of the solutions give rise to Einstein-Weyl structures of dispersionless KP type and dispersionless Hirota (aka hyperCR) type.

On 5-dimensional 2-step homogeneous randers nilmanifolds of Douglas type
In this paper we first obtain the non-Riemannian Randers metrics of Douglas type on two-step homogeneous nilmanifolds of dimension five. Then we explicitly give the flag curvature formulae and the $S$-curvature formulae for the Randers metrics of Douglas type on these spaces. Moreover, we prove that the only simply connected five-dimensional two-step homogeneous Randers nilmanifolds of D...
متن کاملNear-horizon geometries of supersymmetric AdS5 black holes
We provide a classification of near-horizon geometries of supersymmetric, asymptotically antide Sitter, black holes of five-dimensional U(1)-gauged supergravity which admit two rotational symmetries. We find three possibilities: a topologically spherical horizon, an S1×S2 horizon and a toroidal horizon. The near-horizon geometry of the topologically spherical case turns out to be that of the mo...
متن کاملSpacetime Embedding Diagrams for Spherically Symmetric Black Holes
We show that it is possible to embed the 1+1 dimensional reduction of certain spherically symmetric black hole spacetimes into 2+1 Minkowski space. The spacetimes of interest (Schwarzschild de-Sitter, Schwarzschild anti de-Sitter, and Reissner-Nordstrom near the outer horizon) represent a class of metrics whose geometries allow for such embeddings. The embedding diagrams have a dynamic characte...
متن کاملExtremal Black Hole/CFT Correspondence in (Gauged) Supergravities
We extend the investigation of the recently proposed Kerr/CFT correspondence to large classes of rotating black hole solutions in gauged and ungauged supergravities. The correspondence, proposed originally for four-dimensional Kerr black holes, asserts that the quantum states in the near-horizon region of an extremal rotating black hole are holographically dual to a two-dimensional chiral theor...
متن کاملLarge-D gravity and low-D strings.
We show that in the limit of a large number of dimensions a wide class of nonextremal neutral black holes has a universal near-horizon limit. The limiting geometry is the two-dimensional black hole of string theory with a two-dimensional target space. Its conformal symmetry explains the properties of massless scalars found recently in the large-D limit. For black branes with string charges, the...
