Abstract:
The gauging of the qq-Poincar\'e algebra of ref. \cite{qpoincarebic} yields a non-commutative generalization of the Einstein-Cartan lagrangian. We prove its invariance under local qq-Lorentz rotations and, up to a total derivative, under qq-diffeomorphisms. The variations of the fields are given by their qq-Lie derivative, in analogy with the q=1q=1 case. The algebra of qq-Lie derivatives is shown to close with field dependent structure functions. The equations of motion are found, generalizing the Einstein equations and the zero-torsion condition.
