Dirac spin and angular momentum of stationary axisymmetric space–time in the teleparallel gravity

Abstract

In the framework of a teleparallel equivalent to general relativity, stationary axisymmetric space–time in the teleparallel gravity for two different sets of tetrad fields have been investigated. For these sets, we have obtained the expressions for the torsion vector, torsion axial-vector and the angular momentum of the solution. We found that the obtained expressions of the torsion axial-vector and the angular momentum are, in general, quite different in both sets of tetrad fields, while the expressions for the torsion vector have the same value. Moreover, the vector part connected with Dirac spin has been evaluated as well. Finally, special cases of the stationary axisymmetric space–time are discussed.
