Diffeomorphism-invariant noncommutative gravity with twisted local Lorentz invariance
arXiv:0905.3427
Abstract
We propose a new theory of gravitation on noncommutative space-time which is invariant under the general coordinate transformations, while the local Lorentz invariance is realized as twisted gauge symmetry. Our theory is remarkably simpler compared to the existing formulations of noncommutative gravity.
