摘要
We use the Einstein and Papapetrou energy-momentum complexes to calculate the energy and momentum densities of the Weyl metric. Further, using these results we obtain the energy and momentum density components for the Curzon metric (a particular case of the Weyl metric). We find that these two definitions of energy-momentum complexes do not provide the same energy density for Weyl metric, although they give the same momentum density. We show that, in the case of Curzon metric, these two definitions give the same energy only when R --> infinity. Furthermore, we compare these results with those obtained using Landau and Lifshitz, Bergmann and Moller prescriptions.
