标题： Torsion Gravity: a Reappraisal

摘要： 在引力中扭转的作用被进行了批判性回顾。 在描述了涉及扭转物理问题和争议之后，对广义相对论的平行输运等价理论进行了全面阐述。 根据该理论，曲率和扭转是描述引力场的替代方式，因此与引力的相同自由度相关。 然而，更一般的引力理论，例如爱因斯坦-卡坦理论以及针对庞加莱群和仿射群的规范理论，将曲率和扭转视为代表独立自由度。 通过使用强等效原理的主动版本，回顾了一种可能解决这一概念性问题的方法。 此解决方案最终倾向于平行输运的观点，从而支持广义相对论的完备性。 提出了对引力的后果讨论。 显示英文摘要

摘要： The role played by torsion in gravitation is critically reviewed. After a description of the problems and controversies involving the physics of torsion, a comprehensive presentation of the teleparallel equivalent of general relativity is made. According to this theory, curvature and torsion are alternative ways of describing the gravitational field, and consequently related to the same degrees of freedom of gravity. However, more general gravity theories, like for example Einstein-Cartan and gauge theories for the Poincare and the affine groups, consider curvature and torsion as representing independent degrees of freedom. By using an active version of the strong equivalence principle, a possible solution to this conceptual question is reviewed. This solution favors ultimately the teleparallel point of view, and consequently the completeness of general relativity. A discussion of the consequences for gravitation is presented.
