چکیده
We obtain a generally covariant conservation law of energy momentum for gravitational anyons by the general displacement transform. The energymomentum currents have also superpotentials and are therefore identically conserved. It is shown that for Deser’s solution and Clément’s solution, the energy vanishes. The reasonableness of the definition of energy-momentum may be confirmed by the solution for pure Einstein gravity which is a limit of vanishing Chern-Simons coupling of gravitational anyons.

Generally Covariant Conservative Energy-Momentum for Gravitational Anyons
We obtain a generally covariant conservation law of energy momentum for gravitational anyons by the general displacement transform. The energymomentum currents have also superpotentials and are therefore identically conserved. It is shown that for Deser’s solution and Clément’s solution, the energy vanishes.

The N = 1 self-dual supergravity has SL(2,C) symmetry and the lefthanded and right-handed local supersymmetries. These symmetries result in SU(2) charges as the angular-momentum and the supercharges. The model possesses also the invariance under the general translation transforms and this invariance leads to the energy-momentum. All the definitions are generally covariant. As the SU(2) charges ...

The N = 1 self-dual supergravity has SL(2,C) symmetry . This symmetry results in SU(2) charges as the angular-momentum. As in the nonsupersymmetric self-dual gravity, the currents are also of their potentials and are therefore identically conserved. The charges are generally invariant and gauge covariant under local SU(2) transforms approaching to be rigid at spatial infinity. The Poisson brack...
متن کاملEinstein’s Energy-Free Gravitational Field
We show that Einstein’s gravitational field has zero energy, momentum, and stress. This conclusion follows directly from the gravitational field equations, in conjunction with the differential law of energy-momentum conservation T ;ν = 0. Einstein rejected this conservation law despite the fact that it is generally covariant. We trace his rejection to a misapplication of Gauss’ divergence formu...

We consider quantum N = 4 super Yang-Mills theory interacting in a covariant way with N = 4 conformal supergravity. The induced large N effective action for such a theory is calculated on a dilaton-gravitational background using the conformal anomaly found via AdS/CFT correspondence. Considering such an effective action as a quantum correction to the classical gravity action we study quantum co...
