论文摘要
我们讨论$ f（q）$非量子重力的宇宙通货膨胀，其中$ q $是非金属标量。在引入了$ f（q）$重力的共形转换后，我们首先通过研究爱因斯坦框架中不同形式的函数$ f（q）$的相应电势来关注潜在的倾斜通胀。其次，我们研究了约旦框架中特定表格的$ f（q）\ propto q^{2} $的三类通货膨胀潜力的hubble-slow-soll通货膨胀。我们将两种方法的结果与来自Planck和Bicep2/Keck阵列卫星的观察结果进行了比较。也获得了模型的参数空间的观察约束。
We discuss the cosmological inflation in the context of $f(Q)$ non-metric gravity, where $Q$ is the non-metric scalar. After introducing conformal transformations for $f(Q)$ gravity, we first focus on the potential-slow-roll inflation by studying the corresponding potentials for different forms of the function $f(Q)$ in the Einstein frame. Secondly, we investigate the Hubble-slow-roll inflation for three classes of inflationary potentials considered for the specific form $f(Q)\propto Q^{2}$, in the Jordan frame. We compare results in both approaches with observations coming from Planck and BICEP2/Keck array satellites. Observational constraints on the parameters space of the models are obtained as well.
