多方和Chaubergin f（R）-引力模型
Polytropic and Chaplygin f(R)-gravity models
摘要：
我们重建了不同的f（R）-引力模型，分别对应于多变的、标准的Chaubergin、广义的Chaubergin、修正的Chaubergin和修正的可变的Chaubergin气体暗能量模型。我们还得到了描述宇宙加速膨胀的f（R）-引力模型的状态方程参数。我们的结论是，虽然所获得的f（R）-引力的状态方程参数可以表现得像幻影或精粹暗能量模型，他们不能证明从精粹状态的幻影制度的过渡。此外，在de Sitter空间中的多方和Chaubergin f（R）-引力模型都能满足暴胀条件.
英文摘要：
We reconstruct different f(R)-gravity models corresponding to the polytropic, standard Chaplygin, generalized Chaplygin, modified Chaplygin and modified variable Chaplygin gas dark energy models. We also obtain the equation of state parameters of the corresponding f(R)-gravity models which describe the accelerated expansion of the universe. We conclude that although the equation of state parameters of the obtained f(R)-gravities can behave like phantom or quintessence dark energy models, they cannot justify the transition from the quintessence state to the phantom regime. Furthermore, the polytropic and Chaplygin f(R)-gravity models in de Sitter space can satisfy the inflation condition.
