论文摘要
电触电引力是一种修改的重力理论，其中拉格朗日的RICCI标量$ r $被扭转标量$ t $的一般功能所取代。因此，电触电引力中的宇宙学变得非常简化，因为它是二阶理论。本文介绍了$ f（t）$ gravity的完整宇宙学场景，其中$ f（t）= t+β（-t）^α$，其中$α，$和$β$是模型参数。我们介绍了能量密度，压力和状态（EOS）参数方程的曲线。接下来，我们采用了态孔诊断来检查与$λ$ CDM型号的偏差以及暗能量的性质。最后，我们讨论了检查模型一致性的能量条件，并观察到SEC违反了本模型中支持宇宙加速度的当前观察结果。
Teleparallel gravity is a modified theory of gravity in which the Ricci scalar $R$ of the Lagrangian replaced by the general function of torsion scalar $T$ in action. With that, cosmology in teleparallel gravity becomes profoundly simplified because it is second-order theory. The article present a complete cosmological scenario in $f(T)$ gravity with $f(T)=T+β(-T)^α$, where $α,$ and $β$ are model parameters. We present the profiles of energy density, pressure, and equation of state (EoS) parameter. Next to this, we employ statefinder diagnostics to check deviation from the $Λ$CDM model as well as the nature of dark energy. Finally, we discuss the energy conditions to check the consistency of our model and observe that SEC violates in the present model supporting the acceleration of the Universe as per present observation.
