The gravitational angular momentum for the super-energy Bel-Robinson tensor
Lau Loi So
Although the super-energy Bel-Robinson tensor gives a desirable gravitational energy-momentum in a small sphere region, the angular-momentum is vanishing. Intuitively, it should be…
The gravitational energy-momentum for the super-energy Bel-Robinson tensor
Lau Loi So
Describing the gravitational energy-momentum, the super-energy Bel-Robinson tensor is the best candidate. In the past, people seems only explore the lowest order: the electric part…
The Bel-Robinson tensor and the classical pseudotensors
Lau Loi So
Describing the gravitational energy and momentum, the Bel-Robinson tensor is the best tensor. However, the classical pseudotensors can also manage the the same job. As Deser mentio…
Black hole's tidal heating and angular momentum
Lau Loi So
In 1985 Thorne and Hartle used the Landau-Lifshitz pseudotensor to demonstrate the tidal heating and angular momentum flux for a black hole. Later in 2004, Poisson used the gravita…
Dominant property for the Bel-Robinson tensor and tensor S
Lau Loi So
The Bel-Robinson tensor contains many nice mathematical properties and its dominant energy condition is desirable for describing the positive gravitational energy. The dominant pro…
General relativistic tidal heating for Moller pseudotensor
Lau Loi So
Thorne elucidated that the relativistic tidal heating is the same as the Newtonian theory. Moreover, Thorne also claimed that the tidal heating is independent of how one localizes…
The modification of the Bel-Robinson type energy-momentum
Lau Loi So
For describing the non-negative gravitational energy-momentum in terms of a pure Bel-Robinson type energy-momentum in a quasi-local 2-surface, both the Bel-Robinson tensor and…
Application of the 3-space approach to the Bianchi II cosmological model
Lau Loi So
Einstein used 4-dimensional space time geometry to explain gravity. However, in 1962, Baierlein, Sharp and Wheeler proposed a Jacobi type timeless Lagrangian based on the 3-dimensi…
Modification of the Bel-Robinson type energy-momentum
Lau Loi So
For describing the non-negative gravitational energy-momentum in terms of a pure Bel-Robinson type energy-momentum in a quasilocal 2-surface, both the Bel-Robinson tensor and t…
Quasilocal energy-momentum for tensors B and V in small regions
Lau Loi So
The Bel-Robinson tensor and the tensor have the same quasilocal energy-momentum in a small sphere. Using a pseudotensor approach to evaluate the energy-momentum in a half-c…
A simple tensorial proof for the completely symmetric property of the Bel-Robinson tensor
Lau Loi So
The Bel-Robinson tensor was proposed in 1958. The main application of this tensor is for describing gravitational energy. It is known that has many nice prope…
An unique alternative non-negative gravitational energy tensor to the Bel-Robinson tensor in the quasilocal small sphere limit
Lau Loi So
The Bel-Robinson tensor gives a positive definite gravitational energy in the quasilocal small sphere limit approximation. However, there is an alternative tensor $V_{αβ…
Algebraic Rainich conditions for the tensor V
Lau Loi So
Algebraic conditions on the Ricci tensor in the Rainich-Misner-Wheeler unified field theory are known as the Rainich conditions. Penrose and more recently Bergqvist and Lankinen ma…
New positive small vacuum region gravitational energy expressions
Lau Loi So, James M. Nester
We construct an infinite number of new holonomic quasi-local gravitational energy-momentum density pseudotensors with good limits asymptotically and in small regions, both material…
Gravitational energy-momentum in small regions according to the tetrad-teleparallel expressions
Lau Loi So, James M. Nester
The gravitational energy-momentum within a small region as determined by two tetrad-teleparallel expressions is evaluated with the aid of an orthonormal frame adapted to Riemann no…
Classical pseudotenors and positivity in small regions
Lau Loi So, James M. Nester, Hsin Chen
We have studied the famous classical pseudotensors in the small region limit, both inside matter and in vacuum. A recent work [Deser et al.1999 CQG 16, 2815] had found one combinat…
