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…

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…
