This paper is devoted to discuss the attractor solutions of inflationary Chaplygin gas models such as generalized Chaplygin gas, modified Chaplygin gas and generalized cosmic Chaplygin gas in the framework of Randall–Sundrum type II braneworld scenario. We investigate the inflationary parameters like scalar spectral index [Formula: see text], tensor to scalar ratio [Formula: see text], and the running of scalar index [Formula: see text] as a function of e-folding numbers [Formula: see text] in the presence of attractor: [Formula: see text]. We evaluate and reformulate these parameters under high energy condition. In this inflationary scenario, we develop [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text] planes. We also found that these cosmological parameters and perturbation strongly agree with the recent Planck data 2018 for considered Chaplygin gas models instead of [Formula: see text] in case of generalized cosmic Chaplygin gas.

braneworld 情景中的吸引子膨胀解决方案

本文致力于在Randall-Sundrum II型braneworld情景的框架下讨论广义Chaplygin气体、修正Chaplygin气体和广义宇宙Chaplygin气体等暴胀Chaplygin气体模型的吸引子解。我们研究膨胀参数，如标量谱指数 [公式：见文本]、张量与标量比 [公式：见文本]，以及标量指数 [公式：见文本] 作为 e-folding 数的函数 [公式：见文本]在吸引子存在的情况下：[公式：见文本]。我们在高能量条件下评估和重新制定这些参数。在这种通胀情景中，我们开发了[公式：见文本]、[公式：见文本]、[公式：见文本]和[公式：见文本]平面。
