遥平行引力中的惯性和引力

Inertia and gravitation in teleparallel gravity

R. Aldrovandi, Tiago Gribl Lucas, J. G. Pereira

摘要:

利用远平行引力允许引力和惯性分离的事实,得到了引力和惯性能量动量密度的显式表达式。它表明,像所有其他领域的性质,引力单独有一个张量的能量动量密度,在一个一般的框架是保守的协变意义。它们与惯性能动量密度一起形成一个赝张量,这个赝张量在通常意义下是守恒的。本文分析了引力密度和惯性密度在计算引力总能量和动量中所起的作用。

英文摘要:

Using the fact that teleparallel gravity allows a separation between gravitation and inertia, explicit expressions for the gravitational and the inertial energy-momentum densities are obtained. It is shown that, like all other fields of nature, gravitation alone has a tensorial energy-momentum density which in a general frame is conserved in the covariant sense. Together with the inertial energy-momentum density, they form a pseudotensor which is conserved in the ordinary sense. An analysis of the role played by the gravitational and the inertial densities in the computation of the total energy and momentum of gravity is presented.
