论文摘要
在本文中，我们研究了在Swampland ds猜想的情况下的重力理论，称为Mimetic $ F（R，T）$。为此，我们从$ f（r，t）= r+Δt$重力模型引入了Hubble参数H（n）的几种通胀溶液，其中R为RICCI标量，T表示能量孔张量的痕迹。此外，$δ$和$ n $分别是免费参数和许多电子折叠。然后，我们计算诸如电势，拉格朗日乘法器，慢速滚动和一些宇宙学参数之类的数量，例如$ n_ {s} $和$ r $。然后，我们从Swampland DS猜想中挑战上述通货膨胀模型。我们讨论了该模型的稳定性，并研究了这种通货膨胀情况与最新的Planck可观察数据的兼容性或不相容性。
In this paper, we study a theory of gravity called mimetic $f(R, T)$ in the presence of swampland dS conjecture. For this purpose, we introduce several inflation solutions of the Hubble parameter H(N) from $f(R, T)= R+δT$ gravity model, in which R is Ricci scalar, and T denotes the trace of the energy-momentum tensor. Also, $δ$ and $N$ are the free parameter and a number of e-fold, respectively. Then we calculate quantities such as potential, Lagrange multiplier, slow-roll, and some cosmological parameters such as $n_{s}$ and $r$. Then we challenge the mentioned inflationary model from the swampland dS conjecture. We discuss the stability of the model and investigate the compatibility or incompatibility of this inflationary scenario with the latest Planck observable data.
