论文摘要
在一个$ f（ϕ）t $重力的背景下，通货膨胀宇宙重建，其中$ t $对应于能量动量张量的痕迹。为了在通货膨胀时期实现这种重建，我们认为在慢速近似框架的框架内，就$ e $ folds $ n $的数量而言，标量光谱索引$ n_s $。通过假设特定函数$ f（ϕ）$以及最简单的吸引子$ n_s（n）$，我们为重建的有效电位$ v（ϕ）$找到不同的表达式。此外，我们分析了在通货膨胀时期获得的重建后，重新加热的时代。在这种情况下，我们根据状态参数和观测参数的方程来确定再加热时期期间的持续时间和温度。在这种情况下，通过考虑最近的天文观测，与重建模型相关的不同参数受到限制。
The reconstruction of an inflationary universe in the context of one $f(ϕ)T$ gravity, in which $T$ corresponds to the trace of energy momentum tensor is studied. To realize this reconstruction during the inflationary epoch, we consider as attractor the scalar spectral index $n_s$ in terms of of the number of $e$-folds $N$, in the framework of the slow-roll approximation. By assuming a specific function $f(ϕ)$ together with the simplest attractor $n_s(N)$, we find different expressions for the reconstructed effective potential $V(ϕ)$. Additionally, we analyze the era of reheating occurs after of the reconstruction obtained during the inflationary epoch. In this scenario we determine the duration and temperature during the reheating epoch, in terms of the equation of state parameter and the observational parameters. In this context, the different parameters associated to the reconstructed model are restricted during the scenarios of inflation and reheating by considering the recent astronomical observations.
