Abstract
In the SL(2, C) gauge theory of gravitation one obtains a conserved vector current which is analogous to the isotropic spin current of the ordinary SU(2) Yang-Mills theory. In a recent paper Malin has shown that the gravitational conserved current can be defined, and its conservation can be proved, in a spinor affine spacetime without assusming the exitence of a metric tensor, and that a metric structure is required to obtain a decomposition of the current as a sum of contributions of the sources and of the gravitational field itself. In this paper we apply Noether's theorem to obtain a general SL(2, C) invariant form of this conserved current.
