Bel-Robinson张量的另一种非负引力能张量

An alternative non-negative gravitational energy tensor to the Bel-Robinson tensor

Lau Loi So

摘要:

贝尔-罗宾逊张量$B_{αβμν}$在小球极限近似下给出了一个正定的引力能。然而,最近提出了另一种张量$V_{αβμν}$,它提供了与$B_{αβμν}$相同的正性。这两个张量是一个基础的表达式,具有理想的非负引力能在小球区域的限制。

英文摘要:

The Bel-Robinson tensor $B_{αβμν}$ gives a positive definite gravitational energy in the small sphere limit approximation. However, there is an alternative tensor $V_{αβμν}$ which was proposed recently that offers the same positivity as $B_{αβμν}$ does. These two tensors are a basis for expressions which have the desirable non-negative gravitational energy in the small sphere region limit.
