摘要

在本文中,我们以不同的方式引入了减速参数[公式:见正文],提出了一个现代定律。根据这一定律,我们提出了一个时间周期[公式:见正文]。此外,我们还利用这一定律建立了一个模型,在这个模型中,宇宙在四维 FLRW 度量背景下与五子物质一起振荡。利用这个模型,我们得到了振荡哈勃参数[公式:见正文],该参数保持为正值。因此,宇宙周期性地经历减速膨胀和加速膨胀,避免了奇点的出现。

Oscillating quintom scenario with time-dependent periodic deceleration parameter
In this paper, we introduced the deceleration parameter [Formula: see text] in a different manner by proposing a modern law. According to this law, we suggested a time-periodic [Formula: see text]. Furthermore, we used this law to develop a model in which the universe oscillates with quintom matter in a four-dimensional FLRW metric background. Using this model, we obtained the oscillating Hubble parameter [Formula: see text], which remains positive. Consequently, the universe undergoes decelerating expansion and accelerating expansion periodically, avoiding singularities.
