Relating Noncommutative SO(2,3)★ Gravity to the Lorentz-Violating Standard-Model Extension
We consider a model of noncommutative gravity that is based on a spacetime with broken local SO(2,3) ★ symmetry. We show that the torsion-free version of this model is contained within the framework of the Lorentz-violating Standard-Model Extension (SME). We analyze in detail the relation be...
