论文摘要
我们在空间平坦的Friedmann-Lema \^ıtre-Robertson-Walker宇宙中对手性宇宙学的动力学进行详细分析，具有混合的潜在项。固定点分为四个家庭。在发现宇宙学进化中的新阶段时，恢复了文献中的先前结果。从我们的分析中，我们发现了九种不同的宇宙学解决方案，八个描述了缩放溶液，其中一种是无压流体的解决方案，而仅回收了一种De Sitter溶液。
We perform a detailed analysis for the dynamics of Chiral cosmology in a spatially flat Friedmann-Lema\^ıtre-Robertson-Walker universe with a mixed potential term. The stationary points are categorized in four families. Previous results in the literature are recovered while new phases in the cosmological evolution are found. From our analysis we find nine different cosmological solutions, the eight describe scaling solutions, where the one is that of a pressureless fluid, while only one de Sitter solution is recovered.
