摘要

这项工作是基于对Tsallis全息暗能量模型在F（T，TG）引力中的作用的研究。结合幂律尺度因子对对应技术进行了研究。利用该格式得到了状态参数方程。我们计算了速子、精粹、膨胀和k-精粹标量场模型的势能和动力学项，并用图形分析了它们的结果。注意到，Tsallis全息暗能量状态方程参数显示了暗能量在宇宙中的影响。此外，所有标量场模型的动能和势能的图形行为都符合暗能量现象，并与最近的观测结果相支持。

Reconstructed Tsallis Hologhraphic F(T,TG) dark energy model with scalar fields

This work is based on the study of the role of Tsallis holographic dark energy model in

F (T, T_{G})

gravity. We examine correspondence technique together with power-law scale factor. We attain equation of state parameter by using this scheme. We evaluate potential energy and kinetic terms for tachyon, quintessence, dilation and k-essence scalar field models and analyse their results graphically. It is noticed that Tsallis holographic dark energy equation of state parameter shows the influence of dark energy in the universe. Also, the graphical behaviour of kinetic and potential energy for all scalar field models fulfil dark energy phenomenon and the results support with recent observations.
