arXiv:0807.0255 · doi:10.1103/PhysRevD.78.047502 10.1103/PhysRevD.78.069901

Abstract

We show that in the framework of the teleparallel equivalent of general relativity the gravitational energy-momentum of plane-fronted gravitational waves contained in an arbitrary three-dimensional volume V may be easily obtained and is non-negative in the frame of static observers.

One of the conclusions of the paper is changed. The energy-momentum of plane-fronted gravitational waves contained in an arbitrary space volume V is nonpositive
