论文摘要
分析了伽利亚通货膨胀或G通货膨胀率的恒定滚动通胀。通过考虑偶联函数$ g（φ，χ）\ propto g（φ）\，χ^n $对于G通货膨胀模型，我们在恒定滚动通货膨胀的背景下找到了不同的表达式，以适合模型通货膨胀的适当发展。为了获得分析解决方案，我们分析了两种特定情况。 $ g（φ）=φ$和$ n = 0 $，即$ g（φ，χ）\ propto \，φ$，以及$ g（φ）= $ constand和$ n = 1 $当$ g（φ，χ）\ propto \，χ$。在这两种情况下，我们都发现了背景变量重建和框架中的宇宙扰动的不同表达式。我们利用最近的天文观测来限制在恒定滚动条件阶段出现的不同参数，以及耦合函数$ g（φ，χ）$中出现的不同参数。
The constant-roll inflation in the context of Galilean inflation or G-inflation is analyzed. By considering a coupling function $G(φ,χ)\propto g(φ)\,χ^n$ for the model of G-inflation, we find different expressions for a suitable development of a model inflationary in the context of constant roll inflation. In order to obtain analytical solutions, we analyze two specific cases; $g(φ)=φ$ and $n=0$, i.e., $G(φ,χ)\propto\,φ$ and when $g(φ)=$ constant and $n=1$ with which $G(φ,χ)\propto\,χ$. In both cases, we find different expressions for the reconstruction of the background variables and the cosmological perturbations in the framework the constant roll inflation. We utilize recent astronomical observations to constrain the different parameters appearing in the stage of constant roll condition as well in the coupling function $G(φ,χ)$.
