远程并行的正则化作用

Regularizing role of teleparallelism

Tiago Gribl Lucas, Yuri N. Obukhov, J. G. Pereira

摘要:

在协变远程平行框架中讨论了引力能-动量3-形式和超势2-形式的性质,其中Weitzenböck连接表示与框架选择相关的惯性效应。由于其奇怪的渐近行为,惯性效应的贡献往往产生非物理的(发散或平凡的)结果的总能量的系统。然而,在协变远程并行方法中,能量总是有限且非平凡的。远距离平行连接起着正则化工具的作用,它在不扭曲真实引力贡献的情况下减去了惯性效应。作为一个重要的测试的协变形式主义,我们重新分析的史瓦西和克尔解决方案的总能量的计算。

英文摘要:

The properties of the gravitational energy-momentum 3-form and of the superpotential 2-form are discussed in the covariant teleparallel framework, where the Weitzenböck connection represents inertial effects related to the choice of the frame. Due to its odd asymptotic behavior, the contribution of the inertial effects often yields unphysical (divergent or trivial) results for the total energy of the system. However, in the covariant teleparallel approach, the energy is always finite and nontrivial. The teleparallel connection plays a role of a regularizing tool which subtracts the inertial effects without distorting the true gravitational contribution. As a crucial test of the covariant formalism, we reanalyze the computation of the total energy of the Schwarzschild and the Kerr solutions.
