Pseudotensors and quasilocal gravitational energy-momentum
Year: 1998
Type: preprint
Abstract: Early gravitational energy-momentum investigations gave reference frame dependent pseudotensors; subsequently the quasilocal idea was developed. Quasilocal energy-momentum can be determined by the Hamiltonian boundary term, which also identifies the variables to be held fixed on the boundary. We show that a pseudotensor corresponds to a Hamiltonian boundary term. Hence pseudotensors are quasilocal and acceptable; each is the energymomentum density for a definite physical situation with certain boundary conditions. These conditions are identified for the well-known pseudotensors. PACS number(s): 4.20.Cv, 4.20.Fy Typeset using REVTEX
