General relativistic tidal heating for the Mller 58 pseudotensor
Lau Loi So
In his study of tidal stabilization of fully relativistic neutron stars Thorne showed that the fully relativistic expression for tidal heating is the same as in non-relativistic Ne…
The modification of the Bel-Robinson energy-momentum
Lau Loi So
For describing the non-negative gravitational energy-momentum in terms of a pure Bel-Robinson `momentum' in a quasi-local small sphere limit, the Bel-Robinson tensor is desirab…
General relativistic tidal heating for the Moller pseudotensor
Lau Loi So
In his study of tidal stabilization of fully relativistic neutron stars Thorne showed that the fully relativistic expression for tidal heating is the same as in non-relativistic Ne…
Relativistic tidal heating of Hamiltonian quasi-local boundary expressions
Lau Loi So
Purdue and Favata calculate the tidal heating used certain classical pseudotensors. Booth and Creighton employed the quasi-local mass formalism of Brown and York to demonstrate the…
General relativistic tidal work for Papapetrou, Weinberg and Goldberg pseudotensors
Lau Loi So
In 1998 Thorne claimed that all pseudotensors give the same tidal work as the Newtonian theory. In 1999, Purdue used the Landau-Lifshitz pseudotensor to calculate the tidal heating…
An alternative non-negative gravitational energy tensor to the Bel-Robinson tensor
Lau Loi So
The Bel-Robinson tensor gives a positive definite gravitational energy in the small sphere limit approximation. However, there is an alternative tensor which…
Energy-momentum density in small regions: the classical pseudotensors
Lau Loi So, James M. Nester, Hsin Chen
The values for the gravitational energy-momentum density, given by the famous classical pseudotensors: Einstein, Papapetrou, Landau-Lifshitz, Bergmann-Thompson, Goldberg, Møller, a…
Gravitational energy in small regions for the quasilocal expressions in orthonormal frames
Lau Loi So
The Mller tetrad gravitational energy-momentum expression was recently evaluated for a small vacuum region using orthonormal frames adapted to Riemann normal coordinates. Howeve…
Gravitational energy in a small region for the modified Einstein and Landau-Lifshitz pseudotensors
Lau Loi So
The purpose of the classical Einstein and Landau-Lifshitz pseudotensors is for determining the gravitational energy. Neither of them can guarantee a positive energy in holonomic fr…
Gravitational energy from a combination of a tetrad expression and Einstein's pseudotensor
Lau Loi So
The energy-momentum for a gravitating system can be considered by the tetard teleparalle gauge current in orthonormal frames. Whereas the Einstein pseudotensor used holonomic frame…
The modification of the Einstein and Landau-Lifshitz pseudotensrs
Lau Loi So
Deser et al. proposed a combination of the Einstein and Landau-Lifshitz pseudotensors such that the second derivatives in vacuum are proportional to the Bel-Robinson tensor. Stimul…
On source coupling and the teleparallel equivalent to GR
Lau Loi So, James M. Nester
Alternatives to the usual general relativity (GR) Riemannian framework include Riemann-Cartan and teleparallel geometry. The ``teleparallel equivalent of GR" (TEGR, aka GR…
Gravitational energy-momentum in small regions according to Moller's tetrad expression
Lau Loi So, James M. Nester
Moller's tetrad gravitational energy-momentum "tensor" is evaluated for a small vacuum region using an orthonormal frame adapted to Riemann normal coordinates. We find that it does…
The Energy of Bianchi Type I and II Universes in Teleparallel Gravity
Lau Loi So, T. Vargas
For certain models, the energy of the universe which includes the energy of both the matter and the gravitational fields is obtained by using the quasilocal energy-momentum in tele…
A modification of the Chen-Nester quasilocal expressions
Lau Loi So
Chen and Nester proposed four boundary expressions for the quasilocal quantities using the covariant Hamiltonian formalism. Based on these four expressions, there is a simple gener…
