论文摘要
从具有扭转和非金属率的广义射线表方程开始，并考虑到FLRW时空，我们在存在扭转和非金属度的情况下得出了最通用的加速度方程形式。也就是说，当还考虑了非里曼尼亚的自由度时，我们得出了宇宙加速度方程。然后，我们讨论一些条件，在某些条件下，扭转和非金属性加速/减速宇宙的膨胀率。
Starting from the generalized Raychaudhuri equation with torsion and non-metricity, and considering an FLRW spacetime we derive the most general form of acceleration equation in the presence of torsion and non-metricity. That is we derive the cosmic acceleration equation when the nonRiemannian degrees of freedom are also taken into account. We then discuss some conditions under which torsion and non-metricity accelerate/decelerate the expansion rate of the Universe.
