MOND作为有挠引力的推广度规理论的弱场极限

MOND as the weak field limit of an extended metric theory of gravity with torsion

E. Barrientos, S. Mendoza

摘要:

本文构造了一个相对论性的广义度规引力理论,它的弱场极限退化为非相对论性的修正牛顿动力学引力体系。该理论是完全协变的,实现这一点的方法是在引力的描述中引入挠率,以及在引力作用量中加入物质拉格朗日量的一个特定函数。

英文摘要:

In this article we construct a relativistic extended metric theory of gravity, for which its weak field limit reduces to the non-relativistic MOdified Newtonian Dynamics regime of gravity. The theory is fully covariant and the way to achieve this is to introduce torsion in the description of gravity as well as with the addition of a particular function of the matter lagrangian into the gravitational action.
