论文摘要
本文研究了在修改的远期重力理论中加速宇宙扩展的宇宙学。我们讨论了$ f(t,b)$重力理论的宇宙学及其对状态参数方程的新一般形式的含义$ w_ {tb} $,用于解释宇宙的延迟加速,而无需宇宙学恒定场景。我们检查了不同paradigmatic $ f(t,b)$重力模型中$ w_ {tb} $的数值。在这些模型中,$ W_ {TB} $的数值结果在与边界术语B相关的扭转标量t的存在下受到观察,并显示了宇宙的加速膨胀。
This paper studies the cosmology of accelerating expansion of the universe in modified teleparallel gravity theory. We discuss the cosmology of $f(T,B)$ gravity theory and its implication to the new general form of the equation of state parameter $w_{TB}$ for explaining the late-time accelerating expansion of the universe without the need for the cosmological constant scenario. We examine the numerical value of $w_{TB}$ in different paradigmatic $f(T,B)$ gravity models. In those models, the numerical result of $w_{TB}$ is favored with observations in the presence of the torsion scalar T associated with a boundary term B and shows the accelerating expansion of the universe.
