论文摘要
我们考虑了一个爱因斯坦 - 区域标量宇宙学模型，其中以太和标量场正在相互作用。我们考虑的模型包括Kanno等人在文献中提出的两个不同的相互作用模型。以及Donnelly等人。我们通过使用动力学系统的方法对宇宙演化进行扩展分析。具体而言，我们确定固定点，并对这些精确解决方案进行稳定性分析。
We consider an Einstein-aether scalar field cosmological model where the aether and the scalar field are interacting. The model of our consideration consists the two different interacting models proposed in the literature by Kanno et al. and by Donnelly et al. We perform an extended analysis for the cosmological evolution as it is provided by the field equations by using methods from dynamical systems; specifically, we determine the stationary points and we perform the stability analysis of those exact solutions.
