Dirac field and gravity in NC $$SO(2,3)_\star $$ SO(2,3)⋆ model
Abstract Action for the Dirac spinor field coupled to gravity on noncommutative (NC) Moyal-Weyl spacetime is obtained without prior knowledge of the metric tensor. We emphasize gauge origins of gravity and its interaction with fermions by demonstrating that a classical action invariant under SO(2, 3...
