The Colliding Plane Wave and Energy-Momentum Problems in General Relativity and Teleparallel Gravity

Using the energy-momentum complexes of Einstein, Bergmann-Thomson, Landau-Lifshitz (LL), Moller and Papapetrou we have tried to solve energy-momentum and colliding plane wave problems for Bertotti-Robinson (BR) space-time (it has been also a subject of an extensive study in the context of the so-called colliding plane wave problem in General relativity) in General Relativity (GR). Moreover Einstein, Bergmann-Thomson and Landau-Lifshitz (LL) energy-momentum prescriptions have been discussed in Teleparallel Gravity (TP). While Moller and Bergmann-Thomson complexes give exactly same results other energy-momentum complexes do not provide same energy densities. Also we get that both general relativity and teleparallel gravity are equivalent theories
