空间弯曲FRW宇宙中快子场的动力学

Dynamics of tachyon field in spatially curved FRW universe

Jian-Li Li, Jian-Pin Wu

摘要:

研究了空间弯曲FRW宇宙中快子场和正压流体的动力学行为。我们进行了相平面分析,并获得缩放的解决方案,并讨论其稳定性。此外,我们构造了标量势的形式,它可以分别产生空间开放和封闭宇宙的稳定解。

英文摘要:

The dynamics of a tachyon field plus a barotropic fluid is investigated in spatially curved FRW universe. We perform a phase-plane analysis and obtain scaling solutions accompanying with a discussion on their stability. Furthermore, we construct the form of scalar potential which may give rise to stable solutions for spatially open and closed universe separately.
