论文摘要
在本文中,我们使用阶段空间分析研究了最近提出的对MOND的相对论理论。与其先例理论(即三个)不同,该理论据称与观察到的宇宙微波背景和物质功率谱相一致。我们将理论的背景宇宙学方程转换为一组一阶自主方程。然后,我们探索相应的关键点及其物理含义。从某种意义上说,该方法具有强大的意义,即模型的宇宙学行为是独立于理论的自由参数的幅度诊断的。我们表明该理论具有可行的宇宙学时代。尽管使用特定的初始条件,但该理论模仿了标准宇宙学模型。就背景宇宙学而言,它提供了更丰富的结构。这意味着需要进一步的研究来查看该理论是否有助于解决当前的宇宙学紧张局势。
In this paper, we investigate the recently proposed relativistic theory for MOND using the phase space analysis. Unlike its precedent theory, namely TeVeS, this theory is claimed to agree with the observed Cosmic Microwave Background and matter power spectra. We convert the background cosmological equations of the theory to a set of first-order autonomous equations. Then we explore the corresponding critical points and their physical meaning. This method is powerful in the sense that the cosmological behavior of the model is diagnosed independently of the magnitude of the free parameters of the theory. We show that the theory has a viable sequence of cosmological epochs. Although using specific initial conditions, this theory mimics the standard cosmological model; it provides a richer structure as far as the background cosmology is concerned. This implies that further investigations are required to see if this theory contributes to addressing the current cosmological tensions.
