The teleparallel equivalent of general relativity

J. W. Maluf

摘要:

本文综述了广义相对论的遥平行等价。它强调,广义相对论可以制定的四分之一领域和扭转张量,这种几何公式导致替代见解的理论。在度量和曲率张量方面与标准公式的等价性发生在场方程的水平上。本文首先简要介绍了引力的遥平行理论的历史。然后讨论了四维场作为适用于时空中任意观测者的参考系的一般解释,得到了惯性加速度张量。它表明,拉格朗日和哈密顿场方程允许定义的能量,动量和角动量的引力场,作为表面积分的场量。在理论的相空间中,这些量满足庞加莱群的代数。

英文摘要:

A review of the teleparallel equivalent of general relativity is presented. It is emphasized that general relativity may be formulated in terms of the tetrad fields and of the torsion tensor, and that this geometrical formulation leads to alternative insights into the theory. The equivalence with the standard formulation in terms of the metric and curvature tensors takes place at the level of field equations. The review starts with a brief account of the history of teleparallel theories of gravity. Then the ordinary interpretation of the tetrad fields as reference frames adapted to arbitrary observers in space-time is discussed, and the tensor of inertial accelerations on frames is obtained. It is shown that the Lagrangian and Hamiltonian field equations allow to define the energy, momentum and angular momentum of the gravitational field, as surface integrals of the field quantities. In the phase space of the theory, these quantities satisfy the algebra of the Poincaré group.
