平行引力真的等同于广义相对论吗?

Is Teleparallel Gravity really equivalent to General Relativity?

Luciano Combi, Gustavo E. Romero

摘要:

本文给出了广义相对论的遥平行等价公理化。一组形式和语义的假设,阐述了物理意义的理论的各种关键概念的澄清。这些概念包括惯性、洛仑兹不变性和同态不变性以及参考系。它表明,Telepallel引力承认更广泛的时空比广义相对论,允许定义的引力场,如能量和动量,通常被认为是有问题的属性。在这个意义上,虽然两个理论的动力学方程是等价的,但从物理的角度来看,它们是不等价的。最后,公理化公式被用来比较Teleparel重力与其他理论的基础上绝对平行的重力,如非本地和f(T)重力。

英文摘要:

An axiomatization of the so-called Teleparallel Equivalent to General Relativity is presented. A set of formal and semantic postulates are elaborated from where the physical meaning of various key concepts of the theory are clarified. These concepts include those of inertia, Lorentz and diffeomorphism invariance, and reference frame. It is shown that Teleparallel Gravity admits a wider representation of space-time than General Relativity, allowing to define properties of the gravitational field such as energy and momentum that are usually considered problematic. In this sense, although the dynamical equations of both theories are equivalent, their inequivalence from a physical point of view is demonstrated. Finally, the axiomatic formulation is used to compare Teleparallel Gravity with other theories of gravity based on absolute parallelism such as non-local and f(T) gravity.
