Noncommutative symmetries and stability of black ellipsoids in metric affine and string gravity

  title={Noncommutative symmetries and stability of black ellipsoids in metric affine and string gravity},
  author={Sergiu I. Vacaru and Evghenii Gaburov},
  journal={arXiv: High Energy Physics - Theory},
We construct new classes of exact solutions in metric--affine gravity (MAG) with string corrections by the antisymmetric $H$--field. The solutions are parametrized by generic off--diagonal metrics possessing noncommutative symmetry associated to anholonomy framerelations and related nonlinear connection (N--connection) structure. We analyze the horizon and geodesic properties of a class of off--diagonal metrics with deformed spherical symmetries. The maximal analytic extension of ellipsoid type…

Nonlinear connections and spinor geometry

Strong arguments for application of Finsler-like geometries in modern string and gravity theory, noncommutative geometry and noncommUTative field theory, and gravity are emphasized.

Nonholonomic Clifford Structures and Noncommutative Riemann-Finsler Geometry

We survey the geometry of Lagrange and Finsler spaces and discuss the issues related to the definition of curvature of nonholonomic man- ifolds enabled with nonlinear connection structure. It is

Nonlinear connections and exact solutions in Einstein and extra dimension gravity

We outline a new geometric method of constructing exact solutions of gravitational field equations parametrized by generic off–diagonal metrics, anholonomic frames and possessing, in general,



Exact solutions with noncommutative symmetries in Einstein and gauge gravity

We present new classes of exact solutions with noncommutative symmetries constructed in vacuum Einstein gravity (in general, with nonzero cosmological constant), five-dimensional (5D) gravity and

A Method of constructing off diagonal solutions in metric affine and string gravity

The anholonomic frame method is generalized for non--Riemannian gravity models defined by string corrections to the general relativity and metric-affine gravity (MAG) theories. Such spacetime

Horizons and Geodesics of Black Ellipsoids with Anholonomic Conformal Symmetries

The horizon and geodesic structure of static configurations generated by anisotropic conformal transforms of the Schwarzschild metric is analyzed. We construct the maximal analytic extension of such

Generalized Finsler geometry in Einstein, string and metric affine gravity

We develop the method of anholonomic frames with associated nonlinear connection (in brief, N–connection) structure and show explicitly how geometries with local anisotropy (various type of

(Non) Commutative Finsler Geometry from String/M-theory

We synthesize and extend the previous ideas about appearance of both noncommutative and Finsler geometry in string theory with nonvanishing B–field and/or anholonomic (super) frame structures [42,

Geometry and dynamics of the brane-world

Recent developments in string theory have led to 5-dimensional warped spacetime models in which standard-model fields are confined to a 3-brane (the observed universe), while gravity can propagate in

The Large Scale Structure of Space-Time

The theory of the causal structure of a general space-time is developed, and is used to study black holes and to prove a number of theorems establishing the inevitability of singualarities under certain conditions.

The Mathematical Theory of Black Holes

In a course of lectures on the ‘underlying mathematical structures of classical gravitation theory’ given in 1978, Brandon Carter began with the statement ‘If I had been asked five years ago to
