Abstract
In the scope of teleparallel equivalent to general relativity, we are interested in finding the energy–momentum and its suitable quantities of cylindrically axially symmetric rotating (CASR) space–time. We obtain the formulations for the torsion vector, torsion axial-vector, angular momentum and gravitational centre of mass in CASR solutions. We have investigated the gravitational energy–momentum, gravitational flux and matter flux of the space–time. The vector part connected with Dirac spin has been estimated as well. Finally, a special case of the solution are discussed.
