Özet

This study is purposed to elaborate the problem of energy and momentum distribution of string and domain wall in the context of two different approaches of gravity such as general relativity and tele-parallel gravity. In this connection, we have calculated energy-momentum of domain wall and string by using the energy-momentum definitions of Einstein, Bergmann-Thomson and Landau-Lifshitz in general relativity and tele-parallel gravity. In our analysis we obtained that (i) general relativity and tele-parallel gravity are equivalent theories for string and domain wall (ii) different energy-momentum complexes do not provide the same energy and momentum densities neither in general relativity nor in tele-parallel gravity for domain wall.
