f(R)引力理论中的能量-动量复形

Energy-momentum complexes in f(R) theories of gravity

Tuomas Multamaki, Antti Putaja, Elias C. Vagenas, Iiro Vilja

摘要:

尽管在过去的几年里,修正的引力理论,特别是f(R)引力模型引起了人们的广泛关注,但在这些模型的框架内能量局域化的问题还没有得到解决。在目前的工作中,能量动量复合物的概念是在这种情况下。我们将计算能量动量复合体的Landau-Lifshitz公式推广到f(R)引力的框架中。作为一个重要的特殊情况,我们明确计算的能量动量复杂的Schwarzschild-de Sitter度量的一般f(R)理论,以及一些特定的,流行的选择f(R)。

英文摘要:

Despite the fact that modified theories of gravity, in particular the f(R) gravity models have attracted much attention in the last years, the problem of the energy localization in the framework of these models has not been addressed. In the present work the concept of energy-momentum complexes is presented in this context. We generalize the Landau-Lifshitz prescription of calculating the energy-momentum complex to the framework of f(R) gravity. As an important special case, we explicitly calculate the energy-momentum complex for the Schwarzschild-de Sitter metric for a general f(R) theory as well as for a number of specific, popular choices of f(R).
