各向异性引力理论

An anisotropic gravity theory

A. Garcia-Parrado, E. Minguzzi

摘要:

我们研究了Finsler引力的作用量积分,它是通过从切丛拉回一个类爱因斯坦-嘉当拉格朗日量到基流形而得到的。真空方程得到强加相对于任何部分(观察员)的平稳性,以及提出,因为它们是独立的部分。这意味着在真空中度规实际上与速度变量无关,因此动力学与广义相对论一致。

英文摘要:

We study an action integral for Finsler gravity obtained by pulling back an Einstein-Cartan-like Lagrangian from the tangent bundle to the base manifold. The vacuum equations are obtained imposing stationarity with respect to any section (observer) and are well posed as they are independent of the section. They imply that in vacuum the metric is actually independent of the velocity variable so the dynamics becomes coincident with that of general relativity.
