Query: Background independent noncommutative gravity from Fedosov quantization
  of endomorphism bundle   Model of noncommutative gravity is constructed by means of Fedosov
deformation quantization of endomorphism bundle. The fields describing
noncommutativity -- symplectic form and symplectic connection -- are dynamical,
and the resulting theory is completely coordinate covariant and background
independent. Its interpretation in terms of Seiberg-Witten map is provided.
Also, new action for ordinary (commutative) general relativity is given, which
in the present context appears as a commutative limit of noncommutative theory.
