On the Regularization of Kerr-NUT spacetime: I    [PDF]

G. G. L. Nashed

Within the framework of teleparallel equivalent of general relativity (TEGR)
theory, calculation of the total energy and momentum of Kerr-NUT spacetimes
have been employed using two methods of the gravitational energy-momentum,
which is coordinate independent, and the Riemannian connection 1-form,
${\widetilde{\Gamma}_\alpha}^\beta$. It has been shown that the two methods
give the same an unacceptable result, i.e., divergent value. Therefore, a local
Lorentz transformation that plays a role of a regularizing tool, which
subtracts the inertial effects without distorting the true gravitational
contribution, has been suggested. This transformation keeps the resulting
spacetime to be a solution of the equations of motion of TEGR.
