论文摘要
Bianchi形式的稳定性，暗能量（DE）参数化和滚动方面 - $ vi_ {h} $宇宙是用扩展的重力假设提出的。在这里，我们假设了一个最小的耦合几何场字段，其重新功能为$ f（r，t）$由RICCI标量$ r $替换为几何动作。在相关场方程的某些基本条件下寻求精确的解决方案。对于以下理论上有效的前提，该标量调整理论中的字段方程已解决。在适当的条件下观察到，我们的模型显示了加速相变特性的减速。结果观察到结果与最近的观察结果是一致的。在这里，我们的模型预测，随着时间的流逝，宇宙的扩张速度将增加。详细讨论了模型的物理和几何方面。在此模型中，我们还通过将EOS参数$ω（Z）$与RedShift拟合，分析了暗能量的参数化。获得的结果对于阐明暗能量参数之间的关系很有用。在这方面，我们还探索了Swampland暗能量的对应关系。 Swampland标准也已显示出标量场的性质和标量场的潜力。
Stability, dark energy (DE) parameterization and swampland aspects for the Bianchi form-$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.
