In this paper, we have investigated the physical behavior of cosmological models in modified Teleparallel gravity with a general function f(T) = αT + β(−T)n where α,β and n are model parameters and T is the torsion scalar. We have considered a homogeneous and isotropic Friedman universe filled with perfect fluid. We have derived the deceleration parameter q(ω,H(z)) in terms of equation of state (EoS) parameter ω and Hubble parameter H(z). We have investigated the variation of q over the observed values of Hubble constant in various observations within the range of redshift 0.07 ≤ z ≤ 2.30. Also, we have studied effective energy density ρeff, effective pressure peff and effective EoS parameter ωeff. We have observed that the second term of f(T) function behaves just like variable cosmological term Λ (ωeff ≈−1) at late-time universe and causes the acceleration in expansion and works just like dark energy candidates. Also, we have evaluated the age of the present universe for various stages of matter p = ωρ and various f(T) functions.

修正远平行引力中的宇宙模型探索

在本文中，我们研究了宇宙学模型在具有一般函数的修正远程平行引力中的物理行为F(吨) = α吨 + β(-吨)n在哪里α,β和n是模型参数和吨是扭转标量。我们已经考虑了一个充满完美流体的均匀且各向同性的弗里德曼宇宙。我们推导出了减速参数q(ω,H(z))就状态方程 (EoS) 参数而言ω和哈勃参数H(z). 我们研究了变化q在红移范围内的各种观测中超过哈勃常数的观测值0.07 ≤ z ≤ 2.30. 此外，我们研究了有效能量密度ρ效果, 有效压力p效果和有效的 EoS 参数ω效果. 我们观察到第二个术语F(吨)函数的行为就像变量宇宙学术语Λ(ω效果 ≈-1) 在宇宙后期并导致膨胀加速，就像暗能量候选者一样工作。此外，我们还评估了当前宇宙不同阶段的物质年龄p = ωρ和各种F(吨)职能。
