具有f（R，T）引力的Bianchi型$ VI_{h}$宇宙学模型的稳定性、暗能量参数化和沼泽地特征
Stability, dark energy parameterization and swampland aspect of Bianchi Type-$ VI_{h}$ cosmological models with f(R, T)-gravity
摘要：
在一个扩展的引力假说中，对Bianchi形式- $VI_{h}$宇宙的稳定性、暗能量（DE）参数化和沼泽地性质进行了讨论.这里我们假设一个最小耦合几何场，其几何作用量中的重新标度函数$f(R, T)$被Ricci标量$R$取代。在一定的基本条件下，求出了相关场方程的精确解。在下列理论上有效的前提下，标量-张量理论中的场方程已经解出。在适当的条件下，我们的模型显示出减速到加速的相变性质。观察到的结果是一致的，与最近的观察。在这里，我们的模型预测宇宙的膨胀率将随着时间的推移而增加。模型的物理和几何方面进行了详细讨论。在这个模型中，我们还通过用红移拟合EoS参数$ω(z)$来分析暗能量的参数化。所得结果将有助于阐明暗能量参数之间的关系。在此，我们也探讨沼泽地暗能量的对应。沼泽地判据也表明了标量场的性质和标量场的势。
英文摘要：
Stability, dark energy (DE) parameterization and swampland aspects for the Bianchi form-$VI_{h}$ universe have been formulated in an extended gravity hypothesis. Here we have assumed a minimally coupled geometry field with a rescaled function of $f(R, T)$ replaced in the geometric action by the Ricci scalar $R$. Exact solutions are sought under certain basic conditions for the related field equations. For the following theoretically valid premises, the field equations in this scalar-tensor theory have been solved. It is observed under appropriate conditions that our model shows a decelerating to accelerating phase transition property. Results are observed to be coherent with recent observations. Here, our models predict that the universe's rate of expansion will increase with the passage of time. The physical and geometric aspects of the models are discussed in detail. In this model, we also analyze the parameterizations of dark energy by fitting the EoS parameter $ω(z)$ with redshift. The results obtained would be useful in clarifying the relationship between dark energy parameters. In this, we also explore the correspondence of swampland dark energy. The swampland criteria have also been shown the nature of the scalar field and the potential of the scalar field.
