Robertson-Walker时空中标量场的动力学
Dynamics of a scalar field in Robertson-Walker spacetimes
摘要：
我们分析了具有空间曲率的Friedmann-Robertson-Walker宇宙中单个标量场的动力学。我们得到的不动点的解决方案，这是晚时间吸引子。特别地，我们确定了对应于这些稳定解的相应的标量场势。分析是相当普遍的，包括膨胀和收缩的宇宙与积极和消极的标量势。我们证明，已知的幂律，指数，和de-Sitter的解决方案是我们的一般解决方案的某些限制。
英文摘要：
We analyze the dynamics of a single scalar field in Friedmann-Robertson-Walker universes with spatial curvature. We obtain the fixed point solutions which are shown to be late time attractors. In particular, we determine the corresponding scalar field potentials which correspond to these stable solutions. The analysis is quite general and incorporates expanding and contracting universes with both positive and negative scalar potentials. We demonstrate that the known power law, exponential, and de-Sitter solutions are certain limits of our general set of solutions.
