论文摘要
考虑了RSII BRANE重力模型框架中恒定通胀的情况。基于场景，释放第二个慢速参数的较小性，并将其假定为一个常数，可能是统一的顺序。应用汉密尔顿 - 雅各比形式主义，参数的稳定性给出了哈勃参数的微分方程，该方程式导致模型的精确解决方案。重新考虑扰动方程，我们显示标量扰动的幅度出现了一些修改后的术语，而标量光谱索引索引和张量比比率又出现了。将模型的理论结果与观察数据进行比较，确定了模型的自由参数。然后，研究了自由参数的值，该模型与Swampland标准的一致性进行了研究。作为最后一步，考虑了模型的吸引力行为。
The scenario of constant-roll inflation in the frame of the RSII brane gravity model is considered. Based on the scenario, the smallness of the second slow-roll parameter is released and it is assumed as a constant which could be of the order of unity. Applying the Hamilton-Jacobi formalism, the constancy of the parameter gives a differential equation for the Hubble parameter which leads to an exact solution for the model. Reconsidering the perturbation equations we show there are some modified terms appearing in the amplitude of the scalar perturbations and in turn in the scalar spectral index and tensor-to-scalar ratio. Comparing the theoretical results of the model with observational data, the free parameters of the model are determined. Then, the consistency of the model with the swampland criteria is investigated for the obtained values of the free parameters. As the final step, the attractor behavior of the model is considered.
